Answer:
b.-4
Step-by-step explanation:
Because the lower quartile is the lower line on the box and whisker plot
Supplementary angles = 180
2x +3x-10 = 180
5x -10 =180
5x -10 +10 =180+10
5x =190
5x/5 =190/5
x = 38
2x=76
3x-10= 3(38)-10=104
The measure of angles are 76 and 104
Answer: 54x^2 - 330x - 336
step by step explanation:
6 (x-7) x (9x+8)
distribute 6 through the parentheses
(6x - 42) x (9x+8)
multiply the parentheses
54x^2 + 48x - 378x -336
collect like terms
54x^2 - 330x - 336
and thats your answer
hope this helps you :)

Answer:
5 (x-2) (x²+2x+4)
Step-by-step explanation:
Stating with 5x³ - 40, the want to simplify the x part by extracting the common factor, so
5x³ - 40 = 5(x³-8)
Now to factor x³-8, we can rewrite it in the format x³-2³, right?
And there's a formula to obtain x³-y³, which is the Difference of Cubes formula that goes like this: x³-y³= (x-y)(x²+xy+y²)
So, we apply this formula replacing the y with our value of 2:
x³-2³= (x-2)(x²+2x+2²) = (x-2)(x²+2x+4)
So, overall, we have 5x³ - 40 = 5 (x-2) (x²+2x+4)
