Step-by-step explanation:
we know that perimeter of triangle is equals to side + side + side
but we can see that the particular triangle is having all the sides equal so it is seen to be equal lateral triangle and formula of equilateral triangle is 3 × sides.....
So,We will take sides common.....
Perimeter of equilateral triangle= 3×Side
3×4.6 cmsq.
13.8cmsq. Answer
B has the same denominator so there is your answer
Answer: 17
Steps:
1. Plug in (3) into “x” of the g(x) equation:
g(3) = (3)^2 + 4
g(3) = 9 +4
g(3) = 13
2. Plug in g(3) value into “x” of the f(x) equation:
f(g(3)) = x + 4
f(g(3)) = 13 + 4
f(g(3)) = 17
Answer:

Step-by-step explanation:

In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.

Simplify.

Add b to both sides.

Simplify.

Multiply everything by 3 to remove the fractions.

Simplify.
2b + 3b = 45
Simplify.
5b = 45
Divide 5 from both sides.
5b ÷ 5 = 45 ÷ 5
Simplify.
b = 9

So the store bought 9 cases of lightbulbs and in a case, there are 48.
9 * 48 = the number of lightbulbs in the nine cases. 432 is the number of light bulbs in the 9 cases they bought in May. So then let's move on to the cases they bought in June. Do the same thing 8 * 48 is 384. So then add the two amounts together and then you will get 816 which will be your answer. I hope this helps!
