You take the three zeros and put them back with the x s

(x-6)(x+5)(x-2) they are reversed when you put them back in

multiply the first two and get $x^2+5x -6x-30(x-2)$
simplify to $x^2-x-30(x-2)$

Multiply it out again and get $x^3-x^2-30x-2x^2+2x+60$
finally simplify and get $x^3-3x^2-28x+60$

So the answer is the first one

The circumference of the hub cap of a tire is 83.21 centimeters. Find the area of this hub cap. Use

Elena L [17]

Answer:

551 square centimeters

Step-by-step explanation:

Finding the radius (r) :

C = 2πr
83.21 = 2 x 3.14 x r
83.21 = 6.28r
r = 83.21/6.28
r = 13.25 cm

Finding the area :

A = πr²
A = 3.14 x (13.25)²
A = 3.14 x 175.5625
A = 551 square centimeters (nearest whole number)

The area of this hub cap is about 551 square centimeters.

Greta is trying to determine the portion of green candies in various bags of green and yellow candies. Using the information bel

IrinaK [193]

Answer: a) $\dfrac{1}{3}$ b) $\dfrac{71}{100}$ c) $\dfrac{5}{9}$

Step-by-step explanation:

Since we have given that

There are green and yellow candies in each bag.

Bag A: Two thirds of the candies are yellow. What portion of the candies is green?

Part of yellow candies in bag A = $\dfrac{2}{3}$

Part of green candies in bag A would be

$1-\dfrac{2}{3}\\\\=\dfrac{3-2}{3}\\\\=\dfrac{1}{3}$

Bag B: 29 % of the candies are yellow. What portion of the candies is green?

Percentage of candies are yellow = 29%

Portion of candies are green is given by

$1-\dfrac{29}{100}\\\\=1-0.29\\\\=0.71\\\\=\dfrac{71}{100}$

Bag C: 4 out of every 9 candies are yellow. What portion of the candies is green?

Portion of yellow candies = $\dfrac{4}{9}$

Portion of green candies would be

$1-\dfrac{4}{9}\\\\=\dfrac{9-4}{9}\\\\=\dfrac{5}{9}$

Hence, a) $\dfrac{1}{3}$ b) $\dfrac{71}{100}$ c) $\dfrac{5}{9}$

In △ABC, m∠A=16°, m∠B=49°, and a=4. Find c to the nearest tenth.

xenn [34]

Answer:

= 8.33 inches

Step-by-step Explanation

First add 49 + 16, which equals 65, and subtract that result from 180, since a triangle equals 180 degrees and you find out angle C is equal to 115 degrees.

Now using the formula sinA/a = sinB/b = sinC/c, plug in values and you'd get the equation sin49 x 10/sin115. After solving the equation you'd get about 8.32729886047258 inches.

= 8.33
