ANSWER

EXPLANATION
The area of a tra-pezoid is half times sum of the bases times the vertical height.
From the diagram ( see attachment) we use the Pythagoras Theorem to obtain,





This implies that , y=10-4=6ft
The area of tra-pezoid




Answer:
1. 7 (3x + 8y - 22) = 2

2. -2 (4a + 3b-4) = −
8
− 6
+ 8
Step-by-step explanation:
Answer:
x = 8
y = 3
Step-by-step explanation:
x + y = 11
x - y = 5 Subtract
2x = 16
x = 16/2
x = 8
x + y = 11 Substitute x = 8
8 + y = 11 Subtract 8 from both sides
8-8+y =11-8
y = 3
