Answer:

The carpenter will need 3 6-foot long boards in order to make the 8 shelves.

Step-by-step explanation:

Given that a carpinter is installing shelves in two offices, each office will have 4 shelves, and the wood the carpinter wants to use comes in 6foot long boards, the measure of each shelf being 2 1/4 feet long, to determine how many boards he does need, the following calculation must be performed:

1/4 = 0.25

(2 x 4 x 2.25) / 6 = X

(8 x 2.25) / 6 = X

18/6 = X

3 = X

Thus, the carpenter will need 3 6-foot long boards in order to make the 8 shelves.

Answer:

-2 a b + 2 b + 6 a^2 + 9

Step-by-step explanation:

Simplify the following:

2 a^2 + a b + 2 b + 4 a^2 - 3 a b + 9

Grouping like terms, 2 a^2 + a b + 2 b + 4 a^2 - 3 a b + 9 = (a b - 3 a b) + 2 b + (2 a^2 + 4 a^2) + 9:

(a b - 3 a b) + 2 b + (2 a^2 + 4 a^2) + 9

a b + a b (-3) = -2 a b:

-2 a b + 2 b + (2 a^2 + 4 a^2) + 9

2 a^2 + 4 a^2 = 6 a^2:

Answer:  -2 a b + 2 b + 6 a^2 + 9

I need to find the zeros to these two problems and I have no idea how
Iteru [2.4K]
If you have a graphing calculator just put in the equation in 'y=' (not the i equation), and then go to 2nd trace and see where the y=0, those numbers under the x column are the zeros. For the first one, the zeros are: -1, .5, and 2.8. For the second question the zeros are: -3 and about 1.9. The zeros with a decimal are estimations.
