Answer:
y = 4x
Step-by-step explanation:
We need to look at where the line's dots are to find the slope. Between each dot the line goes 1 to the right and 4 up. Remember the saying rise over run to know that the slop is 4/1. 4/1 is just 4 so in the equation we put that next to x.
The next part of making an equation is the y-intercept, or where it crosses the y-axis. Since this hits the y-axis at 0 the complete equation will be
y = 4x + 0
but obviously we don't need to add 0 so the answer is
y = 4x
From the question, we know that:
a = 56
l = 8
w = n - 3
To find the number (n), we should find the width (w) first
General formula of rectangle area is
l × w = a
Input the number to the formula
l × w = a
8w = 56
w = 56/8
w = 7
After finding the width, we find n
w = n - 3
n - 3 = w
n - 3 = 7
n = 10
The number is 10
Answer:
r = 3 ft
Step-by-step explanation:
A = πr²
9π = πr²
9π/π = r²
9 = r²
√9 = r
3 = r
