Answer:

x=3

Step-by-step explanation:

I am assuming that your equation is:

\sqrt{8x + 12}  + 4 = 10

Subtract 4 from both sides to get:

\sqrt{8x + 12}  = 6

Square both sides to get:

(\sqrt{8x + 12})^{2}  =  {6}^{2}

8x + 12 =3 6

8x =24

Divide both sides by 8 to get:

x =  \frac{24}{8}  = 3

What is the m<R???????​
Oksi-84 [34.3K]

Answer:

128

Step-by-step explanation:

Hey There!

So the rule about interior angles of a trapezoid

is that the angles that lie on the segments that are not parallel are supplements

so essentially what I'm saying is that angle R and angle U are supplementary angles so to find x we do

180=15x+8+7x-4

step 1 combine like terms

15+7=22

8-4=4

now we have

180=22x+4

step 2 subtract 4 from each side

180-4=176

now we have

176=22x

step 3 divide each side by 22

176/22=8

so x=8

now we plug in 8 to 15x+8

8x15=120

120+8=128

so we can conclude that angle R = 128

Given that f(x) = x2 + 3x + 6 and g(x) = the quantity of x plus two, over three, solve for f(g(x)) when x = 1
MaRussiya [10]
Easy
f(g(1))
evaluate g(1) then plug thatin for x in f(x)
g(1)=(x+2)/3
g(1)=(1+2)/3
g(1)=1

f(g(1))=
f(1)=(1)^2+3(1)+6
f(1)=1+3+6
f(1)=10
f(g(1))=10
