Answer:
11 and 51
Step-by-step explanation:
1 technically isn't a prime since a prime can only be divided by two things (itself and 1) and 1 can only be divided by 1.
21 can be divided by 1, 3, 7, and 21 so it is not prime.

Answer:

Step-by-step explanation:
Area is the width (6/7 yd) multiplied by the height (1 yd).
6/7 x 1 = 6/7 
In all cases, we will let x represent the number.
1) 54 tens = 540
90 - 540 = -450
x > -450
2) x < 36 and x > 24
24 < x < 36
3) 8 tens and 5 ones = 80 + 5 = 85
x > 85
4) x > 27
x < 33
And the value in the ones place is less than the value in the tens place, so
30 ≤ x ≤ 32
Answer:
7
Step-by-step explanation:
Pythagorean Theorem:
25^2=24^2+x
625=576+x^2
49=x^2
x=sqrt49
x=7
