PLZ HELP IM REALLY CONFUSED WILL MARK BRAINLIEST

Ne4ueva [31]

Answer:

${1.2}^{n} \times 2.5$

Step-by-step explanation:

it's simple my dear friend.

first, she runs 3 miles per week.

so in

${a}^{(n - 1)} \times b$

b is 3. the initial value.

increasement by 20% means she runs 1.2 times than before.

$\frac{100 + 20}{100} = \frac{120}{100} = \frac{12}{10} = 1.2$

then a=1.2

so we have now:

${1.2}^{(n - 1)} \times 3 \\ = {1.2}^{n} \times \frac{3}{1.2} \\ = {1.2}^{n} \times 2.5$

and we got it!

Ivahew [28]

Answer:

$\frac {x^{3}-4x^{2}-20x+32}{x^{3}+2x^{2}-4x-8}$

Step-by-step explanation:

make the denominator same

$\frac{(x^{2}-4)(x-2)}{(x^{2}-4)(x+2) }-\frac{(2x+20)(x+2)}{(x^{2}-4)(x+2)}$

then expand

$\frac {x^{3}-2x^{2}-4x+8}{x^{3}+2x^{2}-4x-8} - \frac {2x^{2}+24x+40}{x^{3}+2x^{2}-4x-8}$

join

$\frac {x^{3}-4x^{2}-20x+32}{x^{3}+2x^{2}-4x-8}$

i think but not sure

inna [77]

Answer:

x = -2, 1/2

Step-by-step explanation:

Step 1: Isolate everything to 1 side

2x² + 3x - 2 = 0

Step 2: Factor

(2x - 1)(x + 2) = 0

Step 3: Find roots

2x - 1 = 0

2x = 1

x = 1/2

x + 2 = 0

x = -2
