Answer:
180 square inches
Step-by-step explanation:
First off since the square will be easiest to do
a=a^2
a=6^2
a=36
now for the triangles
a= height of triangle * base/ 2
a= 12*6/2
a= 36
and since there is 4 of the triangles we multiply 36 by 4
=144
now we add 144 to 36 and we have the total
The equation is a + 9 = 15
Step-by-step explanation:
Let the number be 'a'
Given that,
A number plus 9 is 15
So,
a + 9 =15
a = 15 - 9
a = 6
The equation needed is,
a + 9 = 15
Just move over the two. When you change to standard form you want the x and y together and the constant by itself.
7x-4y+2=0
7x-4y+2-2=0-2
7x-4y=-2
Standard form: 7x-4y=-2
Answer:
<h2>Yes. It's a right triangle.</h2>
Step-by-step explanation:
If a ≤ b < c are the length of the sides of a right triangle, then
a² + b² = c².
We have:
a =30 ft, b = 40 ft and c = 50 ft.
Check the equality:
L = 30² + 40² = 900 + 1600 = 2500
R = 50² = 2500
L = R
