I need help with both of these questions please

tankabanditka [31]

Answer:

$\frac{22}{30} = \frac{11}{15}$

and

$\frac{176}{7} = 25 \frac{1}{7}$

Step-by-step explanation:

First make all the fractions into improper fractions

$1\frac{5}{6} = \frac{11}{6} \\\\2\frac{1}{2} = \frac{5}{2} \\\\3\frac{1}{7} = \frac{22}{7}$

After doing that put them back into the problems

Problem 1)

$1\frac{5}{6}$ ÷ $2\frac{1}{2}$ , plug in the improper fractions

$\frac{11}{6}$ ÷ $\frac{5}{2}$

to divide, you need to flip the second fraction and multiply

$\frac{11}{6}$ · $\frac{2}{5}$ = $\frac{22}{30}$

then reduce

$\frac{22}{30} = \frac{11}{15}$

Problem 2)

$3\frac{1}{7}$ ÷ $\frac{1}{8}\\$

Plug in improper fraction

$\frac{22}{7}$ ÷ $\frac{1}{8}\\$

Then flip second fraction and multiply

$\frac{22}{7}$ · $\frac{8}{1}$

Multiply

$\frac{176}{7}$

Reduce, or make it a mixed number

$\frac{176}{7} = 25 \frac{1}{7}$

Factorize 9(a+1)^2-81

lora16 [44]

Answer:

The answer is 9(a-2)(a+4).

Step-by-step explanation:

Use $a^{2} -b^{2} =(a-b)(a+b)$

$9(a+1)^{2} -81= 9( (a+1)^{2}-9)= 9( (a+1)^{2}-3^{2} )= 9(a+1-3)(a+1+3)\\=9(a-2)(a+4).$
