How do I solve (4x+1)(x-5)=-43x-41
1 answer:
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

Answer:
A = 201.0 mi^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know that r = 8
A = (3.14) *8^2
A = 3.14 * 64
A = 200.96 mi ^2
Rounding to the nearest tenth
A = 201.0 mi^2
X would have to be the variable for 3
I think its 4.8 miles, dont hold me to that though
