Chilee i DONT know I’m just trying to get these points
Answer:
Step-by-step explanation:
Area of figure = area of rectangle 1 + area of rectangle 2 +area of rectangle 3 +area of triangle
= 5*5 + 9*16 +20 * 8 + (1/2) * 3* 3
= 25 + 144 + 160 + 4.5
=333.5 sq. in
Solution:
1) Gather like terms
(3z-43z+2z)
2) Simplify
-38z-4+5
3) Simplify
-38z+1
Done!
Answer:
A. 19.5
Step-by-step explanation:
Diagonals of a rhombus intersect at right angles. Therefore the angle opposite to AD = 90°.
Thus:
90° + x + 3x + 12 = 180° (sum of ∆)
Add like terms
102 + 4x = 180
Subtract 102 from each side
4x = 180 - 102
4x = 78
Subdue both sides by 4
x = 19.5
Answer: x = -7 and y = 10
4x - y = - 38
x + y = 3
y = 3-x
4x - y = - 38
4x -(3-x) = -38
4x - 3 + x = - 38
5x = - 38 + 3
x = - 35/5
x = -7
x + y = 3
- 7 + y = 3
y = 3+7
y = 10
