Answer:
x = 1/2, −1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer: 2.5 ft
Step-by-step explanation:
The volume of a rectangular prism is given by the following formula:
(1)
Where:
is the length of the base
is the width of the base
is the height of the prism
On the other hand, tha area of a rectangle is:
(2)
Then, we can rewrite (1) in terms of (2):
(3)
Now, we know the value of the volume and the area of the base:
Substituting these values in (3):
(4)
Isolating :
This is the height of the truck
C. point because
it is a definition not a term
X^2+3x=24, halve the linear coefficient, square it, and add it to both sides
In this case (3/2)^2=2.25
x^2+3x+2.25=26.25 now the left side is a perfect square...
(x+1.5)^2=26.25 take the square root of both sides
x+1.5=±√26.25 subtract 1.5 from both sides
x=-1.5±√26.25
x=-1.5-√26.25 and -1.5+√26.25
x≈ -6.62 and 3.62
Answer:
14
Step-by-step explanation:
21-3^2+2
3 to the second power is 9
then, 21 - 9 + 2
left to right.....
21 - 9 = 12
12+2=14
