Answer:
The answer to your question is: 35 yd²
Step-by-step explanation:
To solve this problem, just find the data, the formula, substitute the values in the formula and find the result.
Data
Square yards = ?
Length = 21 ft
Width = 15 ft
Formula
Area of a rectangle = length x width
Substitution
Area of a rectangle = 21 ft x 15 ft
Area of a rectangle = 315 ft²
Area of a rectangle = square yards of carpet
Finally, convert ft² to yd²
315 ft² = 35 yd²
Result
Square yards of carpet = 35 yt²
Answer:
10)$38.50
11)D
Step-by-step explanation:
10) n = no. of rides
f(n) + g(n) = 1 + 2.5n
when n=15, 1 + 2.5(15)
= $38.50
11)f(x) = 4x³+3x²-5x+20
g(x) = 9x³-4x²+10x-55
(g-f)(x)=9x³-4x²+10x-55-(4x³
+3x²-5x+20)
= 9x³-4x²+10x-55-4x³
-3x²+5x-20
= 5x³-7x²+15x-75
(Correct me if i am wrong)
Answer:
6(4r+5)
Step-by-step explanation:
Hope this helped!
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
