Answer:
18x
Step-by-step explanation:
The HCF is the highest factor common to both expressions. We can find it by factoring both expressions and identifying common factors.
<h3>Factorization</h3>
36(x³+x²y-12xy²) = 18x·2·(x +4y)(x -3y)
54(x³y+4x³y²-21xy) = 18x·3y·(x +7)(x -3)
The highest common factor is 18x.
d=25 because you would subtract 29 on both sides of the = so you can get your variable, d, alone. So, 54 minus(-) 29 equals 25.
Answer:
20
Step-by-step explanation:
x-2y=6 and x+y=10
Multiply the second equation by 2
2x+2y = 20
$ 295 because you can multiple 15×19.7 is =295.5
Answer:
Is one of them supposed to by x?
Step-by-step explanation:
6x- y = 11
-4x + 5y = 8
With a system of equations, you need to solve for one variable first and the substitute to find the other variables. y is easier to solve for.
6x - y =11 Subtract 6x to both sides.
-y = -6x +11 Multiply by -1 on both sides
y = 6x - 11
We now subsitute y with 6x - 11 in the other equation.
-4x + 5y = 8
-4x + 5(6x-11) = 8
-4x +30x -55 =8
26x = 63
x = 63/26
and now we subsitute this to solve for actual y.
y= 6x -11
y= 6*(63/26)-11
