Answer:

x = 4 \\ x =  - 8

Step-by-step explanation:

x^{2}+4x-40=-8 \\  {x}^{2}  + 4x = 40 - 8 \\  {x}^{2}  + 4x = 32 \\  {x}^{2}  + 4x - 32 = 0 \\ {x}^{2}  + 8x - 4x - 32 = 0 \\ x(x + 8) - 4(x + 8) = 0 \\( x - 4)(x + 8) = 0 \\ x - 4 \:  \:  \:  \:  \:  \: or \:  \:  \:  \:  \: x + 8 = 0 \\ x = 4 \:  \:  \:  \: or \:  \:  \:  \: x =  - 8

Hi I just really need help on this
Komok [63]

Answer:

3. 9 free throws. Proportion: 9/15

4. 18 free throws. Proportion: 18/24

Step-by-step explanation:

Multiply the number of free throws by the decimal of the percentage:

15*60%=15*.60=9

18*75%=18*.75=18.

The proportion is the number of free throws made over the total number of free throws attempted.

Hope this helps! :)
