Answer:

- 8

Step-by-step explanation:

Given

(4 +4 x²)(3x² - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

4(3x² - 5) + 4x²(3x² - 5) ← distribute parenthesis

= 12x² - 20 + 12x^{4} - 20x² ← collect like terms

= 12x^{4} - 8x² - 20

with coefficient of x² term being - 8

3(x+4)-1=-7 plz help
tatiyna

Answer:

x = -6

Step-by-step explanation:

3(x+4)-1=-7

Add 1 to each side

3(x+4)-1+1=-7+1

3(x+4)=-6  

Divide by 3

3/3(x+4)=-6/3

x+4 = -2

Subtract 4 from each side

x+4-4 = -2-4

x = -6

Hi there!

\large\boxed{a = 6 m/s^{2}}

Use the kinematic equation to solve for acceleration:

a = \frac{v_{f}-v_{i}}{t}

Where:

vf = final velocity

vi = initial velocity

t = time

Plug in the given values:

a = \frac{65-35}{5}\\\\a = 30 / 5  \\\\=6 m/s^{2}

Ashley solved the equation for m using the following steps. -4.5 + m = 17 -4.5  -4.5 m = 12.5 What was Ashley’s error?
abruzzese [7]
Ashley's error is that she multiplied m by - 4.5, when she should be adding.


- 4.5 + m = 17 - 4.5 \\  - 4.5 + m = 12.5 \\ m = 17

Hope this helps. - M
