4y + 3 > 23 subtract 3 from both sides
4y > 20 divide both sides by 4
y > 5
-2y > -2 divide both sides by -2 (the order changes)
y < 1

SO SORRY IF THESE IS WRONG:(( JUST SAY IT TO ME NOT TO BULLY ME
<u>Given</u>:
The base of a rectangular prism has an area of 25 square meters. The height of the rectangular prism is 4 meters.
We need to determine the volume of the rectangular prism.
<u>Volume of the rectangular prism:</u>
The volume of the rectangular prism can be determined using the formula,

where B is the base area and h is the height of the prism
Substituting B = 25 and h = 4 in the above formula, we get;


Thus, the volume of the rectangular prism is 100 cubic meters.
Answer:
b= 41
h= 38
Step-by-step explanation:
h= b-3
A= 19b
<u>(b-3) x b</u> = 19 b
2
(b-3) x b = 19b(2)
(b-3) x b = 38b
b-3 = 38
<u>b= 41</u> : h= 41 - 3 =<u>h = 38</u>
I’m not positive if these are correct but this is what I got.

Answer is 6.88 cm
Divide the pentagon radially into five congruent, isosceles triangles. Each triangle has a vertex angle of 360°÷5=72° and altitude of 5÷tan(36°).
radius of circle = 5÷tan(36°) = 6.88 cm
