What is the product of (x-3) and (x+7)?
[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}\diamond[/tex]
First multiply the x's:-
x•x=x²
Now multiply x times 7:-
7x
So we have
x²+7x
Now multiply -3 times x:-
-3x
So we have
x²+7x-3x
Now multiply 7 and -3:-
x²+7x-3x-21
On simplification,
x²+4x-21

Answer:
58.5; 300; 196.5
Step-by-step explanation:
Area of triangle 1 = (1/2) * 9 * 13 = 58.5 inches^2
Area of whole figure = (1/2) * (14+26) * 15 = 300 inches ^2
Area of shaded region = 300 - 58.5 - [(1/2) * 6 * 15] = 241.5 - 45 = 196.5 inches^2
Michael glues pipe cleaners around the edges of a rectangular poster. he uses a total of 14 pipe cleaners with 5 pipe cleaners each on the longer sides of the poster. how many pipe cleaners does he use for each of the shorter sides of the poster?
The total pipe used for each of the shorter sides of the poster is 2 if Michael uses a total of 14 pipe cleaners, with 5 pipe cleaners each on the longer sides of the poster.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We have:
Michael glues pipe cleaners around the edges of a rectangular poster. He uses a total of 14 pipe cleaners, with 5 pipe cleaners each on the longer sides of the poster.
Total pipe Michael uses = 14
He used a total of 5 pipe cleaners on each long side.
Total pipe cleaner on two long sides = 5×2 = 10
The pipe used on shorter side = 14 - 10 = 4
Total pipe for each of the shorter sides of the poster = 4/2 = 2 pipes
Thus, the total pipe for each of the shorter sides of the poster is 2 if Michael uses a total of 14 pipe cleaners, with 5 pipe cleaners each on the longer sides of the poster.

Answer: 21
Step-by-step explanation:
The measure of the tangent to the circle CD = 21
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the 2 tangents to the circle be AE and BD respectively
The measure of the line segment BD = 56
Now , the ratio of the line AE is
AC : AE = 5 : 3
The measure of AE = measure of CD
Let the value of AC = 5x
Let the value of AE = 3x
Now , the measure of AE = measure of BD
Substituting the values in the equation , we get
5x + 3x = 56 be equation (1)
On simplifying the equation , we get
8x = 56
Divide by 8 on both sides of the equation , we get
x = 7
Now , the measure of CD = 3x
Substituting the value of x in the equation , we get
CD = 3 ( 7 ) = 21
Therefore , the measure of CD = 21
Hence , the measure of CD = 21

Idil wants to ride her bicycle 41.4 miles this week. She has already ridden 15 miles. If she rides for 4 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
6.6
Step-by-step explanation:
41.4-15 = 26.4
26.4 divided by 4 equals 6.6
Idil would need to ride an average of 6.6 miles per day for the next 4 days to meet her goal of 41.4 miles for the week.
How find the average number of miles she would have to ride each day to meet her goal?To find the average number of miles Idil would have to ride each day to meet her goal, we can use the following formula:
Average miles per day = (Total miles - Miles already ridden) / Number of days remaining
Given information:
Total miles she wants to ride = 41.4 miles
Miles already ridden = 15 miles
Number of days remaining = 4 days
Now, let's calculate the average miles per day:
Average miles per day = (41.4 - 15) / 4
Average miles per day = 26.4 / 4
Average miles per day = 6.6
So, Idil would need to ride an average of 6.6 miles per day for the next 4 days to meet her goal of 41.4 miles for the week.

Answer:
x=2
Step-by-step explanation:
We must equate f(x)=g(x) ;
x+3=2x^2-3
2x^2-x-6=0, when we solve for x in this equation we get 2 solutions:
x=2, x=-1.5
Since -1.5 is not seen in the table, we consider the value 2.
At x=2 in the table both f(x) and g(x) have the same value 5 and proves f(x)=g(x) has a solution at x=2.
Answer:
x = 2
Step-by-step explanation:
Given:
f(x) = |x| + 3
g(x) = 2x² - 3
From inspection of the table, the equation f(x) = g(x) has a solution when
x = 2 as this is the only value of x when the two functions have the same value of 5.
See attached graph for proof. The points of intersection are the solutions: (-2, 5) and (2, 5). (Since x = -2 is not in the given table, this is not included in the answer to this question).
