find the area of the square whose perimeter is 224cm
Answer:
3,136cm^2
Step-by-step explanation:
A square has 4 sides that are all equal to each other. This means the perimeter can be divided by the number of sides to find the measurement of each side.
224cm ÷ 4 = 56cm
Each side is 56cm
To find the area, we must multiply base and height. Since it is a square, it will be 56cm × 56cm.
56cm × 56cm = 3,136cm^2
Answer:
3136cm²
Explanation:
to find the area of the square, we first need to find the length of one of its sides. the perimeter is the total length of all 4 sides, so we can divide it by 4 to find the length of each side.
224 ÷ 4 = 56
now, we can square this to find the area of the square:
56² = 56 × 56 = 3136
thus, the area of the square is 3136cm².
i hope this helps! :D

2x + y = 12
pls hurry i need badly
[tex] \huge \colorbox{yellow}{Question}[/tex]
[tex]x = y - 3[/tex][tex]2x + y = 12[/tex]
[tex] \huge \colorbox{yellow}{Answer}[/tex]
[tex]x = y - 3 \: (equation \: 1)[/tex]
[tex]2x + y = 12 \: (equation \: 2)[/tex]
Substituting the value of x in
( equation 2)
[tex]2x + y = 12[/tex]
[tex]2(y - 3) + y = 12[/tex]
[tex]2y - 6 + y = 12[/tex]
[tex]2y + y = 12 + 6[/tex]
[tex]3y = 18[/tex]
[tex]y = 18 \div 3[/tex]
[tex]y = 6[/tex]
Now we get y = 6
Substituting the value of y in
( equation 1 )

Answer:
49x + 114
Step-by-step explanation:
[ [ fireplace ] x = area of 5[tex]x^{2}[/tex] ] x + 6
5x
patio = area of 5[tex]x^{2}[/tex] + 49x + 114
5x + 19
(5x + 19) ( x + 6) = 5[tex]x^{2}[/tex] + 19x + 30x + 114
(5[tex]x^{2}[/tex] + 49x + 114) - (5[tex]x^{2}[/tex] ) = 49x + 114
(area of patio and fireplace) - (area of fireplace) = (area of patio only)

A linear function has an x-intercept of -8 and a y-intercept of 4. Which of these is an equation of the linear function?
Answer:
x-2y=-8
Step-by-step explanation:
it is what it is
The equation of the linear function having an x-intercept of -8 and a y-intercept of 4 is y = (1/2)x + 4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A linear function has an x-intercept of -8 and a y-intercept of 4.
So, The two points on the line are (- 8, 0) and (0, 4).
Now, slope(m) = (4 - 0)/(0 + 8).
slope(m) = 4/8.
slope(m) = 1/2.
As it has a y-intercept of 4 it is the value of b, In y = mx + b.
Therefore, The linear function is y = (1/2)x + 4.

Are the two triangles similar? How do you know (What Theorem)?
Answer:
They are similar because of the SAS triangle similarity theorem.
Step-by-step explanation:
The angles in the interconnection of the two triangles are the same because they have the same vertex and lines.
The two sides are similar by a ratio of 1.5.
9/6 and 6/4 both equal to 1.5, which means that they have the same ratio.
Because there is a side that's similar, an angle that's congruent, and then a side that's similar, you can say that the triangles are similar basing on the SIDE-ANGLE-SIDE triangle similarity theorem.

Jacob made two trips to the store. On his first trip to the store, he
bought x kitchen towels for $3 each and y dishcloths for $2 each and spent
a total of $32. On his second trip to the store, he bought x oven mitts for $5
each and returned the y dishcloths he bought on the first trip. He was
refunded the money for the dishcloths and still spent $32. The system of
equations shown below represents the amounts, in dollars, he spent on the
two trips to the store.
3x + 2y = 32
5x - 2y = 32
How many kitchen towels and dishcloths did Jacob buy on his first trip to the
store?
o 10 kitchen towels and 4 dishcloths
o 4 kitchen towels and 10 dishcloths
04 kitchen towels and 8 dishcloths
8 kitchen towels and 4 dishcloths
Answer:
8 kitchen towels and 4 dishcloths!
Step-by-step explanation:
first equation is 3x + 2y = 32
second equation is 5x - 2y = 32
add the two equations together to get 8x = 64
solve for x to get x = 64 / 8 = 8
replace x with 8 in the first equation to get 24 + 2y = 32
solve for y to get y = 8/2 = 4
you have x = 8 and y = 4
first equation becomes 24 + 8 = 32
second equation becomes 40 - 8 = 32
the solution checks out ok.
solution is x = 8 and y = 2 which means he bought 8 kitchen towels and 4 dishcloths on his first trip.

A right triangle has legs that are 5 cm and 7 cm long what is the length of the hypotenuse
1.√12
2.√24
3.√74
4.√144
Answer:
3. 74
Step-by-step explanation:
The pythagorean theorem states that A^2 + B^2 = C^2 (with c being the hypotenuse). So to figure it out we can substitute into the equation.
5^2 = 25
7^2 = 49
25 + 49 = 74
So it would be the square root of 79. I hope this helps! :)
The length of the hypotenuse side of a triangle is √74. Therefore, the correct answer is option 3.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, a right triangle has legs that are 5 cm and 7 cm long.
Let the length of the hypotenuse side be x.
Now, x²=5²+7²
x²=25+49
x²=74
x=√74 units
Therefore, option 3 is the correct answer.
