Answer:
The fabric needs 196.4 ft²
Step-by-step explanation:
∵ The tent formed formed from 4 faces
two equilateral triangles with side length 7 ft
two rectangles with dimensions 11 ft and 7 ft
∵ Area equilateral Δ = 1/4 S²√3
∵ Area rectangle = L × W
∴ The area of the prism = 2 × 1/4 × (7)²√3 + 2 × 7 × 11
= 196.4 ft²
Note:
If you find the area of the triangle by the rule 1/2 × base × height
∴ Area Δ = 1/2 × (7) × 6 = 21 ft²
∴ Area tent = 2 × 21 + 2 × 77 = 196 ft²

Answer:
The answer is option A c=d-ab\a
Step-by-step explanation:
Solution,
here
a(c+b) =d
or, ac+ab=d
or, ac=d-ab
.:c=d-ab/a
hope it helps
good day ❤️✅
(a).
-15ab-6ab^2
= -(15ab+6ab^2)
= -ab(15+6b)
= -3ab(5+2b)
(b).
6x(2y-5)-3(5-2y)
= 6x(2y-5)+3(2y-5)
= (6x+3)(2y-5)
= 3(2x+1)(2y-5)
Tip: If you want to check your answer for (a), you can always simplify it back and see whether it is same as the question.
Hope this helps : )
