Answer:
z-4
Step-by-step explanation:
z(5z²-80) ÷ 5z(z+4) = z-4
Step-by-step explanation:
Given: z(5z²-80) ÷ 5z(z+4)
Calculation:
First we factor numerator z(5z²-80)
Take out 5 from 5z²-80 and we get 5z(z²-16)
Now we factor 16 = 4²
5z(z²-4²)
Using formula, (a²- b²)=(a+b)(a-b)
5z(z²- 4²)⇒5z(z+4)(z-4)
Simplified fraction
5z(z+4)(z-4) ÷ 5z(z+4)
Cancel like factor from numerator and denominator
⇒ z-4
Thus, z(5z²-80) ÷ 5z(z+4) = z-4
Answer:
75%
Step-by-step explanation:
To get the average first you would add up all of the scores, 48+93+78+89+32+92+93. Which equals 525. Then you would divide by the amount of tests (7) so 525/7. Which is 75
Answer:
There is no graph, add a img
Step-by-step explanation:
Step 1 solve (2x-26)°= (x - 13)
Step 2 now solve (7x+8)°= (7x +8)
Step 3 add (x-13) + (7x +8)= 8x - 5 i hope it helps ask me if u didn’t understand or want me to explain something!
