Answer:
Step-by-step explanation:
Since squares are the same length on each side, whatever one side is, if you square it, it will give you the area of the square. To find the length of one side, you need to do the inverse: find the square root of the area.
for example: if you have a square that is 3x3, the are is 3², or 9. Now, in order to find the length of one side, you need to do √9, which gives you 3.
Answer:
C
Step-by-step explanation:
6*12=72
12*8=96
10*12=120
8*6*2/2=48
72+48+96+120=336
Answer:
Step-by-step explanation:
y=-1,869.5x+27,995
Step-by-step explanation:
Let
x-----> the time in years
y----> value of Zachary’s car in dollars
A(0,27,995), B(10,9,300)
step 1
Calculate the slope
The formula to calculate the slope between two points is equal to
m=\frac{y2-y1}{x2-x1}
substitute
m=\frac{9,300-27,995}{10-0}=-1,869.50
step 2
Find the equation of the line
The equation of the line into slope intercept form is equal to
y=mx+b
we have
m=-1,869.50
b=27,995 -----> the y-intercept is the point A
substitute
y=-1,869.5x+27,995
hope this helps have a good day
