Answer is 81
17-8= 9
9 squared is 81
Equation is sqrt81 + 8 = 17
Answer:
P=16+2x
Step-by-step explanation:
The formula for finding the perimeter of a rectangle is P=2l+2w.
Plug the length of 8 and the width of x into the formula.
You'll get P=2(8)+2(x).
Multiply. 2•8=16 and 2•x=2x.
Your expression is P=16+2x.
I hope this helps.
Answer:
12x2 – 75 = 3 (2x+5)(2x – 5)
Step-by-step explanation:
Answer:
<u>Gina's height in inches</u><u>:</u> 63 inches
<u>Noelle's height in inches</u><u>:</u> 67 inches
<u>Equation</u><u>:</u> n + (n - 4) = 130
Step-by-step explanation:
n + (n - 4) = 130
n + n - 4 = 130
2n - 4 = 130
2n - 4 + 4 = 130 + 4
2n = 134
2n ÷ 2 = 134 ÷ 2
n = 67
67 - 4 = 63
Answer:
B
Step-by-step explanation:
Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept
There are two points given on the line: (-1, 2) and (1, -4)
First, find the slope
Reminder: slope is y2-y1/x2-x1
Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3
Now that the slope is found, we can use slope point form
Reminder: slope point form is y-y1=m(x-x1)
Substituting the numbers would give this equation:
y-2=-3(x-(-1))
Simplifying the equation would give y=-3x-1.
