Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
Answer:
7,884
Step-by-step explanation:
Answer:
-0.625
Step-by-step explanation:
-5/8=-0.625
Factor out the common term 2
2(2x + y) = -2
Divide both sides by 2
2x + y = -1
Subtract 2x from both sides
<u>y = -1 - 2x</u>
Answer:
6 and 7
Step-by-step explanation:
You first want to find the factors of 42. They are:
1,2,3,6,7,14,21,42
The factor pairs are:
- 1 & 42
- 2&21
- 3&14
- 6&7
The only factor pair with consecutive numbers is 6 and 7. They are both less than 10 as well, so 6 and 7 works.
