Answer:
x + y = 400
5x + 9y = 2632
Step-by-step explanation:

parallel sides measure :
Area :
height (h) = x
___________________

Therefore, height of Trapezoid is 4 ft
_____________________________

Answer:
x≥
Step-by-step explanation:
given 1.5x+3.75≥5.5
→ 1.5x≥5.5-3.75
→ 1.5x≥1.75
→ x≥
→ x≥
Answer:
B) 112 cm²; 336 cm²
Step-by-step explanation:
The lateral area would be without the bases. In this case, the bases are the top and the bottom
Lateral Area
(2)(2.54)(8) = 40.64
(2)(2.54)(14) = 71.12
Add together and get 111.76 cm²
Surface Area
LA + Bases
<em>Bases</em>
(2)(14)(8) = 224
Add with lateral area and get 335.76 cm²
steps
(x) = 5x^2-3x+7
refine
x=5x^2-3x+7
Switch sides
5x^2-3x+7-x=x-x
Subtract x from both sides
5x^2-4x+7=0
Solve with the quadratic formula
