Answer: 2b^2 • (b^2 + 7b + 4)

Step-by-step explanation:

Step 1 :

Trying to factor by splitting the middle term; Factor b2+7b+4

The first term is, b2 its coefficient is 1 .

The middle term is, +7b its coefficient is 7 .

The last term, "the constant", is +4

Step-1 : Multiply the coefficient of the first term by the constant 1 x 4 = 4

Step-2 : Find two factors of 4 whose sum equals the coefficient of the middle term, which is 7

= 2b^2 • (b^2 + 7b + 4)

I hope this helps.

Use any order, any grouping to write an equivalent expression: 3(2x) + 4y(5) + (4 x 2 x z)

enyata [817]

Answer:

We conclude that the equivalent expression is:

$3\left(2x\right)+4y\left(5\right)+\left(4\times \:2z\right)=6x+20y+8z$

Step-by-step explanation:

Given the expression

$3\left(2x\right)+4y\left(5\right)+\left(4\times \:2z\right)$

Remove parentheses: (a) = a

$=3\times \:2x+4\times \:5y+4\times \:2z$

Multiply the numbers: 3 × 2 = 6

$=6x+4\times \:5y+4\times \:2z$

Multiply the numbers: 4 × 5 = 20

$=6x+20y+4\times \:2z$

Multiply the numbers: 4 × 2 = 8

$=6x+20y+8z$

Thus, we conclude that the equivalent expression is:

$3\left(2x\right)+4y\left(5\right)+\left(4\times \:2z\right)=6x+20y+8z$

Ava bought 7.73 pounds of fruit for a class party. the class ate 3.59 pounds of the fruit. how much fruit is left?

dem82 [27]

Ava bought $7.73$ pounds of fruit for a class party , class ate $3.59$ pounds fruits then $4.14$ pounds fruit left after party.

How can we find how much fruit is left after party ?

Ava bought $=7.73$ pounds fruit

ate by class $=3.59$ pounds fruit

fruit left after party $= total fruit -fruit ate by class$

$= 7.73-3.59\\=4.14$

So $4.14$ pound fruit is left .

Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short race

worty [1.4K]

Answer:

28 short race volunteers

76 long race volunteers

Step-by-step explanation:

Let :

Short races = a

Long races = b

LAST YEAR:

7a + 8b = 804 - - - - (1)

THIS YEAR:

11a + 5b = 688 - - - (2)

Multiply (1) by 5 and (2) by 8

35a + 40b = 4020

88a + 40b = 5504

Subtract

-53a = - 1484

a = 1484 / 53

a = 28

Put a = 28 in equation (1)

7(28) + 8b = 804

196 + 8b = 804

8b = 804 - 196

8b = 608

b = 76

28 short race volunteers

76 long race volunteers
