Hi there!

I believe your answer is:

Here’s why:
⸻⸻⸻⸻
I am assuming that '3=x divided by 3' is supposed to be 
.
⸻⸻⸻⸻
The first, second, and fourth equations have x divided by a number. To isolate x, we would have to use the multiplication property of equality.
⸻⸻⸻⸻
For the third one (
), the variable 'x' is being subtracted by 6. We would have to use the addition property of equality to isolate x.

Hope this helps you. I apologize if it’s incorrect.
Answer:
False
Step-by-step explanation:
A composite figure would be any irregular shapes and can be made up of multiple shapes
Answer: She can by 3 $7.75 books.
Step-by-step explanation:
7.75 times 3= 23.25 so 23.25+24= 47.25 with tax.
Answer:
+
*LN(|
|) +C
Step-by-step explanation:
we will have to do a trig sub for this
use x=a*tanθ for sqrt(x^2 +a^2) where a=2
x=2tanθ, dx= 2 sec^2 (θ) dθ
this turns 
into integral(sqrt( [2tanθ]^2 +4) * 2sec^2 (θ) )dθ
the sqrt( [2tanθ]^2 +4) will condense into 2sec^2 (θ) after converting tan^2(θ) into sec^2(θ) -1
then it simplifies into integral(4*sec^3 (θ)) dθ
you will need to do integration by parts to work out the integral of sec^3(θ) but it will turn into (1/2)sec(θ)tan(θ) + (1/2) LN(|sec(θ)+tan(θ)|) +C
then you will need to rework your functions of θ back into functions of x
tanθ will resolve back into 
(see substitutions) while secθ will resolve into 
sec(θ)= is from its ratio identity of hyp/adj where the hyp. is 
and adj is 2 (see tan(θ) ratio)
after resolving back into functions of x, substitute ratios for trig functions:
= + *LN(||) +C
Answer:
B 84 is our answer
Step-by-step explanation:
triangle formula for surface area is base x height divided by 2 so 7 x 6 = 42 42 ÷ 2 = 21 All the other triangles are going to be the same so 21 x 4 = 84 so 84 is our surface area
