Answer: -30b^2+76b+80
Explanation:
Multiply the second parenthesis by each term from the first parenthesis:
3b•2(-2•2+b+10)+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then distribute 3b•2 through the parenthesis
-24b^2+6b^2+60b+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then collect like terms
-30b^2+60b+40b-32b+8b+80
Collect like terms=
-30b+76b+80

Find the solution set of x: x^2-7x= - 10.
Answer:
(x − 2)(x −5)
Step-by-step explanation:
x² - 7x = - 10
x² - 7x + 10 = 0
Find two numbers that when added together make −7 , and when multiplied make - 10.
The numbers − 2 and −5 fit the criteria.
x2− 7x + 10 = (x − 2)(x −5)
Answer: 4.5 pounds.
Step-by-step explanation:
Given : Weight of original pipe =45 pounds
Weight of first piece = 18 pounds
Then, Weight of other piece = 45- 18 = 27 pounds
Length of first piece = 3 feet
Let x be the length of other piece.
As length is directly proportional to weight.
Then, 

Hence, the he length of the other piece = 4.5 pounds.
