Answer:
Step-by-step explanation:
By Pythagoras Theorem:
Answer:
given p(x)= 5x^3-7x^2-ax-28
(x-4) is a factor of 5x^3-7x^2-ax-28
=>p(4)=0
=>5(4)^3-7(4)^2-4a-28=0
=>320-112-4a-28=0
=>-4a=-180
=>a=180/4
=>a=45
Step-by-step explanation:
x=a
Answer:
I HASVE FORGOTTEN
Step-by-step explanation:
Answer:
$8.50/h
Step-by-step explanation:
I am unsure of the - in the equation. This should be 4h+50+6h+70=M
then we would set the equation equal to the $205
205=4h+50+6h+70
if we simplify we have
205=10h+120
then we would get the h by itself and we get
205-120=10h
85.00=10h
85.00/10=10h/10
8.50=h
