7 0

Answer:

STEP

1

:

Equation at the end of step 1

4x • (2x - 5) = 0

STEP

2

:

Theory - Roots of a product

2.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

shanice is knitting a blanket that requires 1/3 mile of yarn. the fabric store sells yarn in sets of 340 feet.how many full sets
wlad13 [49]
1 mile = 5280 ft.....so 1/3 of a mile is : 1/3 * 5280 = 5280/3 = 1760 ft

and the store sells yarn in sets of 340 ft...
1760/340 = 5.17.....so Shanice would need 6 full sets of yarn......she would actually need a little over 5 sets but since they dont sell half a set, u would round it up to 6 sets

Simplify.<br> 8y-7x+2y² -x-5
Dominik [7]

Answer:

Step-by-step explanation:

we can do like

8y-7x+2y² -x-5

= 2y^2 + 8y - 8x - 5   ( we know that - 5 = 8 - 13)

= 2( y^2 + 4y + 4) - 8x - 13

= 2 (y+2)^2 -8x - 13

I do not know that you wrongly type but here is the answer.
