4(3+5) --> this means that 12/4=3 and 20/4=5 and 4 is the GCF
Hi,
If it is f(x)=2x²+3 and not F(x)=2x²+3 then
Answer D.
Answer:
x=-5
Step-by-step explanation:
10x + 15 = 5x-10
-5x -5x
5x+15 = -10
-15 -15
5x = -25
/5 /5
x = -5
Answer:
11
Step-by-step explanation:
apply pythagoras theorem
Step-by-step explanation:
Given that,
The length of a ladder, H = 20 feet
The height of the wall, h = 15 ft
We know that,

h is perpendicular and H is hypotenuse
So,

Now using Pythagoras theoerm,

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
