Step-by-step explanation:
8. (1)
Area of trapezoid = 1/2(sum of || sides) *perpendicular distance
36 =1/2(x+ y) * 6
36 = ((x + y)*3
36/3 = x + y
12 = x + y
x + y = 12.... (1)
8(2)
It is given that:
x = 2y....(2)
From equations (1) & (2)
2y + y = 12
3y = 12
y = 12/3
y = 4
From equation (2)
x = 2y = 2*4
x = 8
9.
Area of square = 1 square m
Side of square = 1 m
Area of circle = 1 square m

For this case we have the following expression:

Rewriting the expression we have:
1) First we subtract the numbers within the parenthesis:

2) Then, we solve the exponents:

3) Then, multiplication:

4) Finally, the addition of numbers is made:

Answer:
the value of the expression is:
B: 29
3) aₓ = 3x + 2
Plug in numbers for x (for example, 1,2,3,4).
a₁ = 3(1) + 2; a₁ = 3 + 2; a₁ = 5
a₂ = 3(2) + 2; a₂ = 6 + 2; a₂ = 8
a₃ = 3(3) + 2; a₃ = 9 + 2; a₃ = 11
a₄ = 3(4) + 2; a₄ = 12 + 2; a₄ = 14
5, 8, 11, 14, or (C) is your answer
-----------------------------------------------------------------------------------------------------------------
4) 23, 17, 11, 5
Plug in the following numbers to the equations until they match.
C) tₐ = 29 - 6n
when n = 1:
tₐ = 29 - 6(1) ; tₐ = 29 - 6 ; tₐ = 23
tₐ = 29 - 6(2) ; tₐ = 29 - 12 ; tₐ = 17
etc.

hope this helps
Perimeter: 5 + 5 + 5 +5 = 20
area: 5 x 5 x 5 x 5 = 625
A-5.1=1.7
+5.1 on both sides
a=6.8
-31=z+(-17)
+17 on both sides.
-14 = z
