7 is a base, 4 is an exponent.
(a + b)2 Plug in the a and b values
(2 + 3)2 Add 2 and 3
(5)2 Multiply 5 and 2
10
When a = 2 and b = 3, (a + b)2 will equal 1.) 10.
1 < x < 5
Left side is 1 and right is 5
4.5x - 9.5 > 62.5
4.5x > 62.5 + 9.5
4.5x > 72
x > 72/4.5
x > 16 <==
Answer:
2/5x = 3/20 or 2/5 *x = 3/20
Step-by-step explanation:
These are the same thing just different ways to write. The x represents the unknown number
