Answer:

Step-by-step explanation:

(8x - 7)(

The x^2 term has to come out to 8x^2.

The 8 is already there.

So your first term in the second factor is x.

(8x - 7) ( x

Now the question is what is the sign after the x. Since the question shows +7 the only way that can happen is if both signs in the factors are the same.

Since (8x - 7) has been given to you and you need 7 to come out plus, then the sign after x must minus. Both signs must be the same.

(8x - 7)(x -

Last, what comes after the minus sign? You already have a minus 7 so you need something to multiply by 7 to get seven.

That should be a one.

(8x - 7)(x - 1)

x - 1 is you answer. I leave you to check the middle term. It is - 15

Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls = 691. 2 grams

Step-by-step explanation:

The weight of each tennis ball = 57.6 grams

So, the weight of 12 balls = 12 x ( weight of 1 ball)

= 12 x 57.6 grams

= 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls = 691. 2 grams
