Remember pemdas when possible
((1-x)^2)-(-x-2)*(2x+3)
Expand the exponent
(1-x)(1-x)-(-x-2)(2x+3)
Foil the first half
(1-x-x+(x^2))-(-x-2)(2x+3)
Combine like terms in first half
((X^2)-2x+1)-(-x-2)(2x+3)
Foil second half
((X^2)-2x+1)-((-2(x^2))-4x-3x-6)
Combine like terms in second half
((X^2)-2x+1)-((-2(x^2))-7x-6)
Multiply in the negative for the second half
((X^2)-2x+1)+((2(x^2))+7x+6)
Remove unnecessary parentheses
(X^2)-2x+1+2(x^2)+7x+6
Reorganize
2(x^2)+(x^2)+7x-2x+6+1
Combine like terms and you’re done
3(x^2)+5x+7

James is painting a wooden slat fence he had installed around his backyard. The fence has a total of 180 wooden slats. Suppose J
Olenka [21]

Answer:

1 slat every 2 minutes.

Step-by-step explanation:

James is able to paint 2 slats every 5 minutes.

James and Gabe together are able to paint the whole fence (180 slats) in 3 hours and 20 minutes (200 minutes)

The rate of 180 slats in 200 minutes is equal to 18 slats in 20 minutes, and is equal to 9 slats in 10 minutes.

The rate of James is 2 slats in 5 minutes, which is equal to 4 slats in 10 minutes.

Subtracting the rate of James and Gabe together (9 slats in 10 minutes) by the rate of James alone (4 slats in 10 minutes), we have the rate of Gabe, which is 5 slats in 10 minutes, or 1 slat in 2 minutes.

A team fixed a road that was 4,800 m long. After working for 30 days, there was still 1,440 m of the road left to fix. On averag
arlik [135]
The total of the road is 4800 m long. 4800-1440=3360m
We subtract what they have yet to cover from the total to get what they have covered.
So in 30 days they covered 3360 metres.
3660/30 (3660 is divided into 30 equal groups) = 122m
On average they covered 122 metres per day.

Amy wants to carpet a room that is 12 feet by 8 feet. How many square yards of carpet will she need to complete the room?
Elodia [21]
Firstly, you should find how many square yard is in one square foot.
One square yard= Nine square feet.
then, in order to find the area, you need to multiply 12 by 8, which gives you 96 square feet.
In order to find the square feet, you need to divide 96 by 9 (as 1 square yard is equal to 9 square feet)
When you divide these, you get 10.66
Therefore, Amy needs 10.66 square yards of carpet.
Hope this helps :)
