$3150 because 9% of $25000 is $2250 and 15% of $6000 is 900 and 2250+ 900 is 3150
-50 because if he owes 10 different people the same amount it would be -50 because he owes them money
We need to find two numbers that multiply to 24 (last coefficient) and add to 10 (middle coefficient). Through trial and error, the two values are 6 and 4
6 + 4 = 10
6*4 = 24
So we can break up the 10ab into 6ab+4ab and then use factor by grouping
a^2 + 10ab + 24b^2
a^2 + 6ab + 4ab + 24b^2
(a^2+6ab) + (4ab+24b^2)
a(a+6b) + 4b(a+6b)
(a+4b)(a+6b)
Therefore, the original expression factors completely to (a+4b)(a+6b)
Answer:
y=-1/2x-3
Step-by-step explanation:
Let's pick two points for slope.
For the y-inctercept, the line intersect at the y-axis at (0,-3)
CHECK:
16% of 231 is 36.80
16% + 84% = 100%
36.80+ 231 = $267.80
Ans = $267.80
