Remember you can do anything to an equation as long as you do it to both sides
expand by foiling or distributing
4x²-19x-5=-43x-41
add 43x to both sides and add 41 to both sides
4x²+24x+36=0
factor
facotr out of 4
4(x²+6x+9)=0
factor inside
what 2 numbers multiply to get 9 and add to get 6?
3 and 3
4(x+3)(x+3)=0
set to 0
x+3=0
x=-3
x=-3 is answer
3a+2.25=3a+1.75
Implies 3a+2.25=3a+1.75+.5
Answer is 0.5
Answer:
A=2pi(9) I think
Step-by-step explanation:
Answer:
x = 7/12
Step-by-step explanation:
We start off by multiplying both sides by 4:
4(x-2) = 3(2-x)
Distribute the 4 and the 3:
4x - 8 = 6 - 3x
Bring all the terms with the x at the first side:
4x + 3x = 6 + 8
7x = 12
x = 7/12
