Just switch the x and the 3
Answer:
10 yellow marbles
Step-by-step explanation:
(y is the amount of yellow marbles)
y=2x-2
y=2(6)-2
y=12-2
y=10
Rectangle B = 56inches by 28inches
It’s pretty easy you just multiply 8 by 7 and 4 by 7.
15 x 0.20 = 3
15 - 3 = 12
answer: reduced price 12
A]
3x^3y+15xy-9x^2y-45y
=3x^3y+3*5x*y-3*3x^2*y-3*15y
factoring 3y we get:
3y(x^3+5x-3x^2-15)
B]
Factoring the expression we get:
3x^3y+15xy-9x^2y-45y
=3xy(x^2+5)-9y(x^2+5)
=(3xy-9y)(x^2+5)
