B. 1116 in2
C. 1080 in2
D. 1188 in2

Answers

Answer 1

Answer: ok so we have 3 rectangles and 2 triangles
area of rectangle=legnth times width
area of traingle=1/2 times base times height

24 times 20+15 times 20+15 times 20+1/2 times 9 times 24+1/2 times 9 times 24=1296
answer is A

After that you do 600 divided by 28 then by 78 then you will find the answer.

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except -3. Which of thefollowing describes the domain of (gof)(x)?
all real values except X -3 and the x for which fex) 7
all real values except X -3 and the x for which f(x) -3
all real values except x 7 and the x for which f(x) 7
all real values except x * 7 and the x for which f(x) -3

Answers

Answer:

Third choice

Step-by-step explanation:

The domain of f(x) is the set of all real values except 7, i.e $x\ne7$

and the domain of g(x) is the set of all real values except -3, i.e $x\ne -3$

The domain of $g\circ f$ is the set of all real numbers x in the domain of $f$ such that $f(x)$ is in the domain of $g(x)$ .

However any numbers that are excluded from the domain of f must also be excluded from the domain of $g\circ f$ .

Therefore the correct choice is all real values except x=7 and the x for which f(x) =7

Answer:

Pretty sure its 21/4 = 5 1/4 L, not sure tho...

Step-by-step explanation:

Divide 3 1/2 by 2/3.

3 1/2 = 7/2 as an improper fraction,

7/2 ÷ 2/3

= 7/2 * 3/2

= 21/4 = 5 1/4 L

Would the answer be negative or positive -18-(-12)

Answers

the answer will be negative

It will be negative:
-18 - (-12)
When there is minus ( - ) and minus( - ), it becomes plus ( + )
so lets rewrite it:
-18 + 12
-6 will be the answer

And the answer is negative.
