Answer:

9

Step-by-step explanation:

x^{2}  - 36 = 5x

x^{2} - 36 = 5x

x^{2} -5x = 36

9^{2} - 45 = 36

  + 45  + 45

-----------------------

81 = 81 ✅

9^{2} - 36 = 5(9)

81 - 36 = 45 ✅

What is the area of this trapezoid? Enter your answer in the box.
olga2289 [7]
The formula for area of a trapezoid is
\frac{(b1 + b2) \times h}{2}
so you add up the bottom base (17) and the top base (3) to get 20.
you then take the sum of the bases (20) times the height (8) to get 160.
lastly, you take 160 ÷ 2 to get your final answer, which is 80 (:

Answer:

C=0.65M+22.65

Step-by-step explanation:

The standard charge includes an initial fee and plus an addditional fee for each mile driven and is given by:

S=0.40M+17.75

The insurance charge is given by:

I=0.25M+4.90

So, the total charge C will be the sum of the standard charge S and the insurance charge I:

C=S+I

Substitute:

C=(0.40M+17.75)+(0.25M+4.90)

Rearrange:

C=(0.40M+0.25M)+(17.75+4.90)

Add:

C=0.65M+22.65

And we have acauired our equation relating C to M!
