Answer:
2x^4 - 9x^3 -8x^2 + 15x
Step-by-step explanation:
(x^2-5x)(2x^2+x-3) distribute first
2x^4
x^2 + x = x^3
5 * 2x^2 x= 10x^3
5x^1+1 = 5x^2
5 * 3x = 15x Put them all together
2x^4 + x^3 - 3x^2 - 10x^3 - 5x^2 + 15x Like terms
2x^4 + x^3 -10x^3 - 3x^2- 5x^2 + 15x Add similar terms
= 2x^4 + x^3 - 10x^3 - 8x^2 + 15x more adding terms
2x^4 - 9x^3 -8x^2 + 15x
Hope my answer has helped you, if not i'm sorry.
7 in, because any value than 7 either makes more than 16 when doubled, or makes it so that the width has to be 0, which would make it a line and not a rectangle.
2/3 = 0.666
4/5 = 0.8
so, 4/5 is closer to 1
Answer: x=90
Step-by-step explanation: Okay let's see! Let's solve your equation step-by-step.
x
42
=
15
7
Step 1: Cross-multiply.
x
42
=
15
7
x*(7)=(15)*(42)
7x=630
Step 2: Divide both sides by 7.
7x
7
=
630
7
x=90
Answer:
divide the fraction by itself then multiply it by 10
