Answer:84f+57g
Step-by-step explanation:
First, multiply everything in parenthesis.
Multiply the 6 by 8f+10g, and the 4 by 3g+9f.
This gets you 48f+60g+9g-12g+36f.
After that, just solve it like normal.
You get 84f+57g.
Answer:
a
Step-by-step explanation:
Answer:
B) p<5
Step-by-step explanation:
You would multiply 6 by 3 and x by 4. You would end up getting 4x = 18 and then you simplify that to get 9/2 or 4.5.
Ok, so the quadratic coefient is 1, so great
take 1/2 of the linear coefient and square it
10/2=5, (5)^2=25
add that to both sides
x^2+10x+25=7+25
factor perfect square trionomial
(x+5)^2=32
squaer root both sides
x+5=+/-4√2
minus 5
x=-5+/-4√2
x=-5+4√2 and -5-4√2
