Answer:
D) 2x² + 4x - 30
Step-by-step explanation:
Follow the FOIL method:
FOIL =
First
Outside
Inside
Last
...and is the order you multiply to solve:
(x + 5)(2x - 6) =
(x)(2x) = 2x²
(x)(-6) = -6x
(5)(2x) = 10x
(5)(-6) = -30
Combine like terms. Simplify:
2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30
2x² + 4x - 30 is your answer.

Step-by-step explanation:
To solve this you would use trigonometry. You would draw a triangle and mark the lower angle between the diagonal and horizontal line as 60. Then you would label the adjacent side as 50ft.
This means you are looking for the opposite and have the adjacent
To find the height you would do:
tan60 = Height÷50
Height = 50 tan60 = 86.6 feet (to 3 sf)
Answer:
i saw my name but i think the anwerser i the third one
Step-by-step explanation:
Standard form is
ax+by=c
where a,b,c are integers
y+3=1/4x
timesboth sides by 4
4y+12=x
minus x both sides
-x+4y+12=0
minus 12 both sides
-x+4y=-12
(I like x to be positive so)
times both sides by -1
1x-4y=12
a=1
b=-4
c=12
