C+(4−3c)−2=0

simplify step-by-step.

c+4−3c−2=0

c+4+−3c+−2=0

(c+−3c)+(4+−2)=0(Combine Like Terms)

−2c+2=0

−2c+2=0

Subtract 2 from both sides.

−2c+2−2=0−2

−2c=−2

Divide both sides by -2.

−2c/−2 = −2/−2

c=1

I NEED ANSWERS TO THESE QUESTIONS

I only have the answer for 1, but !

1. The area of a parallelogram is base times height. Since the area of that rectangle is twice the area of the circle, then the area of the circle is half the base times the height. It will be half of 2πr· r. The area of the circle will be πr2

Compare 6 ⋅ 108 to 3 ⋅ 106.

djverab [1.8K]

Answer:

$6*10^8$ is 200 times larger than $3*10^6$

Step-by-step explanation:

$6*10^8\ and \ 3*10^6$

To compare both values we divide the exponents

$\frac{6*10^8}{3*10^6}$

6 divide by 3 is 2

for simplify exponents we use exponential property

a^m / a^n = a^(m-n)

$\frac{10^8}{10^6}=10^2$

$\frac{6*10^8}{3*10^6}=2*10^2= 200$

$6*10^8$ is 200 times larger than $3*10^6$

The length of a rectangle is nine inches more than its width. Its area is 486 square inches. Find the width and length of the re

Elan Coil [88]

Answer:

width: 18 in
length: 27 in

Step-by-step explanation:

The relations between length (L) and width (W) are ...

W +9 = L

LW = 486

Substituting gives ...

(W+9)W = 486

W^2 +9W -486 = 0 . . . put in standard form

(W +27)(W -18) = 0 . . . . factor

W = 18 . . . . the positive solution

The width of the rectangle is 18 inches; the length is 27 inches.

Comment on factoring

There are a number of ways to solve quadratics. Apart from using a graphing calculator, one of the easiest is factoring. Here, we're looking for factors of -486 that have a sum of 9.

486 = 2 × 3^5, so we might guess that the factors of interest are -2·3² = -18 and 3·3² = 27. These turn out to be correct: -18 +27 = 9; (-18)(27) = -486.
