Idk, sorry. try to include a picture
For question number 3
-7, 7, 6, -4,
4, -2, -1, 1
0, 2, 3, -3,
5, -5, -6, 8
For question number 4:
-4, 1, -10, 3,
-9, 2, -3, 0,
5, -8, -1, -6,
-2, -5, 4, -7
X = width
2x = length
2x + 4x = 48
6x = 48
x = 8
2x = 16
8*16 = 128
Your answer should be that the area is 128 square yards. Hope this helps!
First, subtract both sides by 8x and you would get:
1 - 11x = 3
Then, subtract both sides by 1 and you will get:
-11x = 2
Divide both sides by -11:
x = -2/11
Answer:
the third side is 4.
Step-by-step explanation:
Using Pythagorean theorem of a^2 + b^2 = c^2 for right triangles, substitute
the numbers to show (
+ 
= 
and solve for b. The square root and square cancel each other out, so you get 65 + = 81.
Subtract 65 from both sides to get = 16.
Then take the square root of both sides to get b = 
which equals 4.
