Pretend the stuff under it cannot be touched when adding or subtracting
so (square root of 15) + (square root of 15) =
2(square root of 15)
14) 23.24778564
15) 38.01327111
The last one, I also need help
ANSWER: x = 4 ( 8 + 160 )
STEP BY STEP:
Let's start by getting a variable to represent the number. Let's use x. ⇩
x=
Now we know that there is a sum of 8 and 160. Let's add them to each other ⇩
x= 8 + 160
Now we know that this will be multiplied. Let's put parentheses around the addition to symbolize this.
X= (8 + 160)
Finally multiply this by four, making your equation
x= 4 (8 + 160)
I don't know the options but from looking at the problem I'm assuming the answer is
x = 4 ( 8 + 160 )
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m =
=
