(5a + 2bc) (5a - 2bc)
Answers
The product of (sum of 2 things) (difference of 2 things) = (difference in their squares).
For example: (x + y) (x - y) = (x² - y²)
When you're trying to factor algebra expressions, it's always good to keep your
eyes open for the difference of two squares, and remember that it's going to be
(sum) x (difference) of the things that they're squares of.
Here you have (a sum) x (a difference) of the same 2 things:
(5a + 2bc) (5a - 2bc)
You can multiply them out, or just use the little tool above:
(5a)² = 25a²
(2bc)² = 4b²c²
So (their sum) x (their difference) is (25a² - 4b²c²) .

Answer:
8
Step-by-step explanation:
- Divide, if possible. Check each answer. -144-:18
assuming the question is -144 : (-18) and not -144-:18
-144 : (-18) = 8
-----------------
check
8 × (-18) = -144
Answers
So,
A pays £125
B pays £x
They pay in the ration 3:2
Therefore,
125/x = 3/2
Cross multiplying we get,
125 x 2 = 3x
3x = 250
x = £63.33

Answer:
1a. y=550(8) + 25
1a. the yer of this problem is 25 because it is a real number. it represents your Y-intercept because they are getting paid $550 an hour and getting paid an additional $25 for doing the job. The slope of this problem would be $550 because that is how much they are getting paid an hour.
