Answer:

Step-by-step explanation:

7) 2ab + 4ac = 2*a*b + 2 *2 *a*c

= 2a(b + 2c)

$\dfrac{2ab^{2}c}{2ab+4ac}=\dfrac{2*a* b^{2}*c}{2a(b+2c)}\\\\\\\text{2a in the denominator and numerator get cancelled}\\\\ = \dfrac{b^{2}c}{b+2c}$

8) ac - a²c² = c( a - a²c)

bc - abc = c(b - ab)

$\dfrac{ac - a^{2}c^{2}}{bc-abc^{2}}=\dfrac{c(a-a^{2}c)}{c(b-ab)}\\\\$

$=\dfrac{a-a^{2}c}{b-abc}$

9) b²+ 4b - 5 = b² + 5b - 1b - 5

= b(b + 5) - 1(b + 5)

= (b +5)(b - 1)

b² + 8b + 15 = b² + 5b + 3b + 15

= b(b + 5) + 3(b + 5)

= (b + 5 )(b + 3)

$\dfrac{b^{2}+4b-5}{b^{2}+8b+15}=\dfrac{(b+5)(b-1)}{(b+5)(b+3)}\\\\\\$

$=\dfrac{b-1}{b+3}$

5 is a coefficient. A coefficient is a number multiplied by a variable.

(2y+13) is a factor. It can be multiplied by 8 to get an extended answer.

-1 is a constant. A constant is a number that does not change.

Hope this helps!

There is 3/4 of pizza leftover from the night before . how many 1/8 portions are there

serg [7]

We want to know how many 1/8's are in 3/4, so we divide.

$\sf\dfrac{3}{4}\div\dfrac{1}{8}$

Flip the 2nd fraction and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{1}$

Multiply the numerators and denominators together:

$\sf\dfrac{3\times8}{4\times1}\rightarrow\dfrac{24}{4}$

Divide:

$\boxed{\sf6}$
