Answer: c) 28
<u>Step-by-step explanation:</u>
x² - 7x + 10 ; x = -2
replace x with -2:
(-2)² - 7(-2) + 10
= 4 - -14 + 10
= 4 + 14 + 10
= 18 + 10
= 28
23. 1/2(18)(10)=90 ft
24. 1/2(9)(6)=27 ft
sorry i don’t know 25
Answer:
150 pages
Step-by-step explanation:
want to read 2,000 pages
already read 1,250 pages
Number of pages left to read
= 2000-1250
= 750
Rest of the reading spread over 5 weeks
wants to read same number of pages each week
Number of pages that need to be read each week over 5 weeks
= Number of pages left to read / total number of weeks
=750 / 5
= 150
He will need to read 150 pages a week.
Answer:
The answer is: C. 3my^4 - 3my^2x
Step-by-step explanation:
For the problem:
3my^2 (y^2x - x) =
Multiply each term by 3my^2:
3my^2 * y^2x - 3my^2 *x =
3my^4x - 3my^2x
Explanation
The sum of the three angles of a triangle has to be equal to 180 degrees.
So...
180-(75+50)
180-125
=55 degrees
X equals 55 degrees
