Answer:
90 ft²
Step-by-step explanation:
Given the sides of similar figures in the ratio a : b, then
ratio of areas = a² : b²
Here ratio of sides = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the surface area of the new solid is 9 times the first
SA = 9 × 10 = 90 ft²
Answer: 
Step-by-step explanation:
To find the inverse of a function replace f(x) with x and the original x with y
Now we can solve for y
Square both sides so we can cancel out the root
Now subtract 7 from both sides
Now replace y with the inverse of f(x), 
Answer:
I think 3 ,4 ,and 5 are to only correct ones
Answer:
x=2
Step-by-step explanation:
5(7-x)-3(x+4)-4=4(x-3)+7
35-5x-3x-12-4=4x-12+7
19-8x=4x-5
+8x. +8x
24=12x
x=2
