It is to be noted that the square root of 7-2√10 is √5-√2. See the explanation below.
What is the square of a number?It is to be noted that square root, in mathematics, refers to a factor of a number which when multiplied by itself, results in the original number. For example, both 3 and –3 are square roots of 9.
Hence the solution to the above expression or problem is given as stated below:
7-2√10 = 5 + 2 - 2 2√10
= (√5)² + (√2)² - 2(√5)(√2)
Hence
7-2√10 = (√5 - √2)²
√(7-2√10) = √5 - √2

What was the average rate of change from week 1 to week 4?
how would i go about solving this
The average rate of change from week 1 to week 4 is 3 animals per week.
What is mean?It should be noted that a mean simply refers to the average set of numbers that are given.
This will be illustrated as thus:
The total number of rate of change animals from week 1 to week 4 will be:
= (73 - 62) + (78 - 73) + (86 - 78)
= 11 + 5 + 8.
= 24
Therefore, the average will be:
= Total changes / Number of weeks
= 24 / 8.
= 3
Therefore, there's an average of 3 animals added every week.

Angle #1 = 90 Reason: Every angle of a rectangle measures 90°. Opposite sides are equal and parallel. It has 2 diagonals of equal length.
# 22= 90. Reason: Every angle of a rectangle measures 90°. Opposite sides are equal and parallel. It has 2 diagonals of equal length.
# 8 = 90 . Reason: Every angle of a rectangle measures 90°. Opposite sides are equal and parallel. It has 2 diagonals of equal length.
# 2 = 90. Reason: A right triangle is a type of triangle that has one angle that measures 90°.
#17 = 60. Reason: We have the sum of all interior angles at 180.
180 degrees = 30+ 90+ #17
so # 17 = 180 - ( 30+90) = 60.
#23= 90. Reason: A right triangle is a type of triangle that has one angle that measures 90°.
# 19= 90. Reason: Opposite sides are equal and parallel. It has 2 diagonals of equal length.
#26 = 90. Reason: Opposite sides are equal and parallel. It has 2 diagonals of equal length.
#21 = 90. Reason: Opposite sides are equal and parallel. It has 2 diagonals of equal length.
# 16 = 60 Reason: We have the sum of all interior angles at 180. And Opposite sides are equal and parallel. So # 16 + 90 + # 27 = 180
so # 16 + #27 = 180-90 = 90.
#3= 30. We have # 16 +# 3 = 90. So 60 +# 3 = 90. Hence, # 3 = 30.
#27 = 30.

Three vertices of a parallelogram are shown in the figure below.
Give the coordinates of the fourth vertex.
Answer:
(-5, -3)
Step-by-step explanation:
We can use the fact that the diagonals of a parallelogram bisect each other
Let me classify the points as
A (-4, 7)
B (2, -5)
C (3, 5)
Let us assume the 4th vertex is D(x, y) where x and y have to be determined
We will assume that AB is the diagonal of the parallelogram ABCD
The midpoint of a line segment from (x1, y1) to (x2, y2) is given by
(1/2)(x1 + x2, y1 + y2) ie the average of their x and coordinates
If we let O be the midpoint of AB, coordinates of O are
1/2 x (-4 + 2, 7 -5) = 1/2 x ( -2, 2) = (-1, 1)
We know the other diagonal CD must pass through point O and O is also the midpoint of CD
Therefore if coordinates of D are (x, y)
then x-coordinate of O which is -1 should be the average of x coordinate of C and x coordinate of D
==> - 1 = (3 + x)/2
=> -2 = 3 + x
=> -2 - 3 = x
=> -5 = x
=> x = -5
Similarly
1 = (5 + y)/2
=> 2 = 5 + y
=> 2 - 5 = y
=> -3 = y
y = -3
So the coordinate of the fourth vertex D are (-3, -5)

The equivalent fractions shown on the fraction bar are 4/6 and 12/18.
The divisor is 3.
What are the equivalent fractions?A fraction is a non whole number that is made up of a numerator and a denominator. The numerator is the number above the line and the denominator or divisor is the number below the line. An example of a fraction is 1/10. 1 is the numerator and 10 is the denominator.
Equivalent fractions are fractions that have different numerators and denominators but when expressed in its simplest form, they are the same fractions. For example, 1/2 and 3/6 are equivalent fractions because when 3/6 is expressed in its simplest form, it is 1/2.
In the first fraction bar given, there are 4 bars and 3 are shaded. Thus, the fraction it represents is 4/6. Likewise in the second fraction bar, 6 are shaded and there are 8 bars.
In the third fraction bar, 12 are shaded and there are a total of 18 bars. The fraction is 12/18. In the fourth fraction bar, 4 are shaded and there are 6 total bars. The fraction is 4/6.

Define equivalent ratios.When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, the ratios 1:2 and 2:4 are equivalent. If two or more ratios have the same value when reduced to their most basic form, they are said to be equal. For instance, the ratios 1:2, 2:4, and 4:8 are identical. When reduced to their most basic form, all three ratios have the same value, or 1:2. We can multiply or divide the words by a natural number to get analogous ratios to a given ratio. When two words are co-prime (have just one other common factor), we multiply them by any natural number instead of performing the division procedure.

What is defined as the triangle?A triangle is a 2-dimensional closed shape with three sides, three angles, and three vertices. A triangle is a type of polygon.
The sum of a triangle's three interior angles is always 180°.The sum of any two triangle sides is always larger than the length of a third side.A triangle's area is equal to half the product of the its base and height.For the given value of triangle;
The three angles are given as;
3x + 84x + 1184By the sum of all angles of triangle property.
The sum of all three angles of the triangle is 180°
Thus,
3x + 8 + 4x + 11 + 84 = 180
Simplifying;
7x = 180 - 103
7x = 77
x = 11
Thus, the solution of x of the given triangle is found as x = 11.

Find the value of the exterior or interior angle!
The values of interior angle is 63°, 46°, 71°
What are Interior Angles?
Angles inside a polygon are referred to as interior angles. A triangle, for instance, has three interior angles. Interior angles are sometimes defined as "angles enclosed in the interior region of two parallel lines when they are intersected by a transversal."
Put all the values equal to 180°,
=> (2x+5) + (x+17) + (3x-16) = 180°
Now, solve this equation and find x,
=> 6x + 22 - 16 = 180
=> 6x = 180 - 6
=> x = 174 / 6
=> x = 29°
Put x = 29° in the 2x + 5, x + 17, 3x - 16
2x + 15 | x + 17 | 3x - 16
2 * 29 + 15 | 29 + 17 | 3 * 29 - 16
63° | 46° | 71°
Therefore, the values of interior angle is 63°, 46°, 71°
