Answer:
The two numbers are 7 and 11.
Step-by-step explanation:
x represent the first number.
y represent the second number.
x + y = 18
x - y = 4
2x = 22
x = 11
x - y = 4
(11) - y = 4
y = 7
Answer:
8.5
Step-by-step explanation:
To find √72, we must factor 72, remembering that the factor 36 is a perfect square:
√72 = √2·√36, or 6√2. Ashton failed to take the square root of the factor 2 of 72.
√72 = 6√2, and √2 is approx. 1.414.
Multiplying 1.414 by 6 results in 8.5, which is to the nearest tenth.
