X can be anything you want it to be.
I would stick with something easy for x.
y=4(x)^2
y=4(2)^2
y=4(4)
y= 16
Answer:
5 m
Step-by-step explanation:
Set up an equation using the square area formula, A = s²
Let x represent the original side length:
(x + 3)² = 64
Simplify:
x² + 6x + 9 = 64
Subtract 64 from both sides:
x² + 6x - 55
Factor by finding 2 factors of -55 that add up to 6:
(x + 11)(x - 5) = 0
Solve for the 2 solutions:
x + 11 = 0
x = -11
x - 5 = 0
x = 5
The side length cannot be be negative, so the answer is 5.
The side length of the original square is 5 m.
Answer:
the answer is 1.5 because converting them into their fractional form indeed informs u that 1.5 is thus greater than 2.25 BT lesser than 1
The correct answer is distance, in miles, between the cities
Hope this helped :)
Answer:
The answer is 18
Step-by-step explanation:
<h3><u>Given</u>;</h3>
A car uses 30 gallons of gasoline for a trip of 750 miles.
<h3><u>To </u><u>Find</u>;</h3>
Gallons would be used on a trip of 450 miles.
Now, Gasoline used for one mile
30 ÷ 750 = 0.04
So,
0.04 × 450 = 18
Thus, 18 gallons would be used on a trip of 450 miles.
