Answer:
AB = 21
Step-by-step explanation:
BC and DE are sides of a regular pentagon, so their lengths are equal.
5x - 4 = 2x + 11
3x = 15
x = 5
All sides are congruent, so AB = BC = 5x - 4
AB = BC = 5x - 4
AB = 5(5) - 4
AB = 25 - 4
AB = 21
The answer is 37.68 because you first find the area of the circle which is pie r^2 or 50.24 then you find the fourth of that which is 12.56 so you subtract 12.56 from 50.24 to get the answer of 37.68
X= -4/3
x=1/2
Those are the only two
Answer:
5.6 * (4 + p)
Step-by-step explanation:
<u>Step 1: Make an expression
</u>
5.6 times -> 5.6 *
Sum of 4 and a number p -> (4 + p)
<u>Equation:</u> 5.6 * (4 + p)
Answer: 5.6 * (4 + p)
