Answer:
Option 3)............... I guess so
Perimeter = (2 × Length) + (2 × Width)
If the length is dependent on the width (because the length is 10 more than the width), we can say that L = W + 10.
To find the answer to the Peri, we have to find out what the W is first.
184 = 2(W + 10) + 2W
184 = 2W + 20 + 2W
184 = 4W + 20
184 - 20 = 4W = 164
164 ÷ 4 = W
41 = W
We have found out width. Our length is W + 10, so L = 41 + 10 = 51
W = 41 and L = 51
I'm 17 and I'm in my Junior year of high school.

a trapezoid
equation for area = h(a +b) ÷ 2
so you sub that in
8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120
so the area is 120cm
8
A trapezoid
equation for area = h(a +b) ÷ 2
so you sub that in
6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42
So the answer is 42 inches
9
A kite
equation for area = p× q ÷ 2
so you sub that in
(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3
So the answer is 33 cm
sorry I can't see 10s measurements
These 2 angles are "vertical angles." Thus, angle 1 = angle 4.
Therefore, 6x+1 = 8x-17. Solving for x, 2x = 18 and x = 9 (answer)
