tbh i havent checked so sorry if its wrong
The answer to 100.5 divided by 1.5 is 67
Hey
The Answer is -4x
Heres the Step by Step work
You add 14 to each side because it is negative, so
5x-14=-34
+14|+14
and you will end up with
5x=-20
Divide 5 on each side, so
5x=-20
/5x | /5x
-20 / 5x =
x=-4
or
-4x
mark branliest plz
Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms
= 2(x² + 6x) + 14
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9 ) + 14
= 2(x + 3)² - 18 + 14
= 2(x + 3)² - 4 ← in vertex form
We know that:
A = 1440
H = 32
So you need to work backwards to find base.
1440 / 32 = 45
We can check our work:
32 x 45 = 1440
B = 45
