1 answer:

4 0

$(x-2)(x^2+3x-5)\qquad\text{use distributive property}\\\\=(x)(x^2)+(x)(3x)+(x)(-5)+(-2)(x^2)+(-2)(3x)+(-2)(-5)\\\\=x^3+3x^2-5x-2x^2-6x+10\qquad\text{combine like terms}\\\\=x^3+(3x^2-2x^2)+(-5x-6x)+10\\\\=\boxed{x^3+x^2-11x+10}$

What is negative one eighth of a number is -3/4 as an equation?<br> will name the brainliest!

topjm [15]

Answer:

The equation is $-\frac{1}{8}$ x = $-\frac{3}{4}$

Step-by-step explanation:

The Equation is formed from two sides equal to each other

In the algebraic statement "is" means equal

In the algebraic statement "of" means times (×)

∵ One eighth means $\frac{1}{8}$

∴ Negative one eighth means $-\frac{1}{8}$

→ Assume that the number is x

∵ "of" means times

∴ Negative one eighth of a number = $-\frac{1}{8}$ × (x)

∴ Negative one eighth of a number = $-\frac{1}{8}$ x

∵ Negative one eighth of a number is $-\frac{3}{4}$

→ "is" means equal, so the left side is $-\frac{1}{8}$ x and the right side is $-\frac{3}{4}$

∴ $-\frac{1}{8}$ x = $-\frac{3}{4}$ ⇒ Equation

∴ The equation is $-\frac{1}{8}$ x = $-\frac{3}{4}$
