The answer is 8x.
You are combining like terms as 5 and 3 both have x so you are simply adding 5+3= 8
Answer:
C. 14.1 inches
Step-by-step explanation:
Use the formula for the area of a square, A = s²
Plug in the area:
200 = s²
14.1 = s
So, C is correct
Will got 12 and John got 24.
You would set the equation as:
36=n+2n
Combine like terms
36=3n
Divide 3 from both sides
12=n
If you want to check it
12+2(12)=36
12+24=36
36=36
Answer:
Step-by-step explanation:
We are to find critical values for the test given
a) df =16: Alpha = 0.01 and right tailed
Critical value= 2.583
b) df = 23-1 = 22: alpha = 0.1 and left tailed
critical= -1.717
c)df=31-1 =30: alpha =0.1: two tailed
t =1.697
Critical values can be obtained from critical t tables.
Left tailed will have negative sign and right tailed positive
Answer:
3
Step-by-step explanation:
y = 3 - 1/2x
rewrite equation so the slope is in front
y = -1/2x + 3
plug in 0 for x
y = -1/2(0) + 3
solve for y
y = 0 + 3
y = 3
y- intercept = (0,3)
