Rewrite in simplest terms: -10(-3m-10)-3(-8m+3) i don't usually ask questions that often but I actually need help this time. so

andreev551 [17]

Answer:

The simplest form is 6m+91.

Step-by-step explanation:

Consider the given information.

$-10(-3m-10)-3(-8m+3)$

First, remove the parenthesis by multiplying -10 and -3 inside the parenthesis.

$30m+100-24m-9$

Now, rearrange the like terms.

$30m-24m+100-9$

Combine the like terms.

$6m+91$

Hence, the simplest form is 6m+91.

Simplify the expression given below. x+2/4x^2+5x+1 * 4x+1/x^2-4

GenaCL600 [577]

Answer:

$\frac{1}{(x+1)(x-2)}$

Step-by-step explanation:

$\frac{x+2}{4x^2 + 5x + 1} \ \times \ \frac{4x+1}{x^2-4}\\\\=\frac{x+2}{4x^2 + 4x + x + 1} \ \times \ \frac{4x+1}{x^2-2^2}\\\\=\frac{x+2}{4x(x + 1) + 1( x + 1)} \ \times \ \frac{4x+1}{(x - 2)(x + 2)} \ \ \ \ \ \ \ \ [ \ (a^2 - b^2 = (a-b)(a+b) \ ]\\\\\\=\frac{x+2}{(4x + 1)(x+1)} \ \times \ \frac{4x+1}{(x-2)(x+2)}\\\\=\frac{1}{(x+1)} \ \times \ \frac{1}{(x-2)}\\\\= \frac{1}{(x+1)(x-2)}$
