Area = length * width
(10x + 6)(9x + 8)
Multiple (I used rainbow method)
10x * 9x = 90x^2
10x * 8 = 80x
6 * 9x = 54x
6 * 8 = 48
90x^2 + 80x + 54x + 48
90x^2+ 134x + 48
The area is 90x^2 + 134x + 48

Item 32 On three 150-point geography tests, you earned grades of 88%, 94%, and 90%. The final test is worth 250 points. What per
stira [4]
97.2% on the final.
Find the total amount of points needed to get a 93%. 150+150+150+250 = 700 total points. 700*.93 = 651 total points needed to get 93%. find the points received from the other quizzes and subtract the sum from 651 to find how many points need to be scored on the final.
150*.88=132 (test 1)
150*.94=141 (test 2)
150*.90=135 (test 3)
132+141+135= 408

651-408 = 243 points to score on the final exam.
243/250 =.972 or 97.2%

Answer:

y = 23x-82

Step-by-step explanation:

The equation is written in the form y = mx+b

We need to find the slope

m = (y2-y1)/(x2-x1)

   = (79-56)/(7-6)

   = 23/1

The slope is 23

y= 23x +b

Put in a point for x and y to determine b

10 =23(4) +b

10 =92 +b

Subtract 92 from each side

10-92 = 92-92 +b

-82 =b

The equation is

y = 23x-82
