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
Answer:
175 ft
Step-by-step explanation:
Let c represent the change in altitude. Then an equation can be written:
150 +c = 325
We solve for c by subtracting 150 from both sides of the equation:
c = 325 -150 = 175
The change in altitude is an increase of 175 feet.
_____
This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...
c = 325 -150 = 175 . . . . as above.
The - change every sing -m-3n+12
