Add: x^5 - 4x^4 + 7x^3 + 8, 9x^3+ 7x^2 - 10, and -2x^5 + 7x^4 - 3x + 8.
Nastasia [14]

Answer:

\large\boxed{-x^5+3x^4+16x^3+7x^2-3x+6}

Step-by-step explanation:

(x^5 - 4x^4 + 7x^3 + 8)+(9x^3+ 7x^2 - 10)+(-2x^5 + 7x^4 - 3x + 8)\\\\=x^5 - 4x^4 + 7x^3 + 8+9x^3+ 7x^2 - 10-2x^5 + 7x^4 - 3x + 8\\\\\text{combine like terms}\\\\=(x^5-2x^5)+(-4x^4+7x^4)+(7x^3+9x^3)+7x^2-3x+(8-10+8)\\\\=-x^5+3x^4+16x^3+7x^2-3x+6

If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?
8_murik_8 [283]

Answer: option B

Step-by-step explanation:

The circumference of a circle can be calculated with this formula:

C=2\pi r

Where "C" is the circumference of the circle and "r" is the radius of the circle.

The area of a circle can be calculated with:

A=\pi r^2

Where "r" is the radius.

Knowing the area, you can solve for the radius:

r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm

Substituting into  C=2\pi r, you get that the circumference of this circle is:

 C=2\pi (3cm)=6\pi\ cm

How do you solve by substitution in algebra?
Elden [556K]
Ok so lets say we have a system of equations:

y = x + 1
x + y = 5

All you would do is plug in what is equal to the variable so:

x + x + 1 = 5

Then you would just simplify and solve

2x + 1 = 5
       -1   -1
_________

2x = 4

the width of a rectangle is twice as long as the length. if the length is increased by 50% and the width is decreased by 20%, th
evablogger [386]

Answer:

Width: 160

Length: 80

Step-by-step explanation:

Width = 2x and length = x

X + 0.5x + 2x - 0.4x = 248

3.1x = 248

X = 248/3.1

X = 80

Width = (2)(80) and length = 80
