Answer: $918.49

Step-by-step explanation: 135.26 + 108.23 = 243.49

90 * 5 = 450

90 * 2.5 = 225

243.49 + 450 + 225 = 918.49

What is the product? (3x-6) (2x^2 -7x+1)
STALIN [3.7K]

<u>Answer-</u>

\left(3x-6\right)\left(2x^2-7x+1\right)=6x^3-33x^2+45x-6

<u>Solution-</u>

Given the two polynomials are 3x-6, 2x^2 -7x+1

So their product will be,

=\left(3x-6\right)\left(2x^2-7x+1\right)

Distributing the Parentheses,

=3x\cdot \:2x^2+3x\left(-7x\right)+3x\cdot \:1+\left(-6\right)\cdot \:2x^2+\left(-6\right)\left(-7x\right)+\left(-6\right)\cdot \:1

Applying minus-plus rules,

=3\cdot \:2x^2x-3\cdot \:7xx+3\cdot \:1\cdot \:x-6\cdot \:2x^2+6\cdot \:7x-6\cdot \:1

Simplifying further,

=6x^3-33x^2+45x-6

Twice the sum of a number and 10 is -20
Reptile [31]
Let, the number = x

Then, 2(x + 10) = -20

2x + 20 = -20

2x = -20 - 20

x = -40/2

x = -20

In short, The number would be: -20

Hope this helps!
