Mark plans on taking 3 trips this summer. He'll drive 143 miles,138 miles , and 141 miles. Estimate the total miles he'll drive.

Deffense [45]

Lets round each distance to the nearest tens place, and then add them up to get an estimate. 143 rounds down to 140, 138 rounds up to 140, and 141 rounds down to 140. So: 140 + 140 + 140 = 420 miles

Last year ,Chesa made 32 one-cup servings of soup for a school party . This year, she will make two times the amount of the soup

Gnoma [55]

Answer:

Chesa will make 4 gallons of soup this year.

Step-by-step explanation:

If you multiply 32 times 2 you will get 64. You then find out how many cups are in a gallon. If 16 cups are in a gallon, you then divide 64 by 16. Your answer should be 4.

Factor completely y^2-xy-56x^2

olga2289 [7]

You can factor this out by thinking of the factors of 56 that have a sum of -1. 7 and 8 are factors of 56 and to get a sum of -1, 8 should be negative. 7 + -8 = -1

So $y^{2} - xy - 56x^{2}$ factored out is (y+7x)(y-8x)

We can check this using FOIL
F = (y)(y) = $y^{2}$
O = (y)(-8x) = -8xy
I = (7x)(y) = 7xy
L = (7x)(-8x) = $-56x^{2}$
$y^{2} - 8xy + 7xy - 56x^{2}$ Combine like terms
$y^{2} - xy - 56x^{2}$
