We have that
0 = –2x²<span>+ 2x + 3
</span>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
(–2x²+ 2x)=-3
Factor the leading coefficient
-2*(x²-x)=-3
Complete the square. Remember to balance the equation by adding the same constants to each side
-2*(x²-x+0.25)=-3-0.50
Rewrite as perfect squares
-2*(x-0.5)²=-3.50
(x-0.5)²=-3.50/-2
(x-0.5)²=1.75------> square root both sides
(+/-)(x-0.5)=√7/2
(+)(x-0.5)=√7/2----> (√7/2)+0.5----> x=1.823
(-)(x-0.5)=√5/2-----> x=0.5-(√7/2)----> x=-0.823
the solutions are
x=1.823
x=-0.823
X=4 you have to write it out as 6x+8=32 the subtract 8 from both sides so it will say 6x=24 then divide 6x and 24 (both sides) by 6 and it is x=4
Answer:
You go to whoever's question you wanna answer and it should say "add answer" and just type out your answer and solve it
120 inches cubed (^3)
To find the volume of a rectangular prism, the formula is base area • height. We just have to solve this problem.
The two sides of the base 8 and 5. 8 • 5 = 40, so the area of the base = 40.
Then, the height is 3. 40 • 3 = 120, so the volume is 120 inches^3
<span>3^2 + 4^2 = 5^2
answer is </span>A) 3^2 + 4^2 = 5^2
