A polynomial is factored using algebra tiles. An algebra tile configuration. 0 tiles are in the Factor 1 spot and 0 tiles are in

MatroZZZ [7]

Polynomials consist of both indeterminates and coefficients. The polynomial that was factored in is x² - 2x - 8.

<h3>What are polynomials?</h3>

A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.

Given to us

1 is labeled x squared,

2 are labeled x,

4 tiles below x squared are labeled negative x,

8 tiles below the x tiles are labeled negative.

As we know that algebra tiles are the tiles that represent variables or coefficients. Also, the shape of the tiles can be rectangle or square.

These tiles can be represented as,

1 is labeled x squared, = x²

2 are labeled x, = 2x

4 tiles below x squared are labeled negative x = -4x

8 tiles below the x tiles are labeled negative = -8

Sum all the terms we will get,

x² + 2x - 4x - 8

x² - 2x - 8

Hence, the polynomial that was factored in is x² - 2x - 8.

the ratio of the measures of the three angles in a triangle is 2:9:4. find the measures of the angles

givi [52]

Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°

If an object is propelled upward from a height of s feet at an initial velocity of v feet per second, then its height h after t

irina [24]

Answer:

At 1.5 seconds and 2.5 seconds

Step-by-step explanation:

Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.

$68=-16t^2+64t+8$

Set that equal to 0 and factor to solve for t:

$-16t^2+64t-60=0$

Using the quadratic formula, we get t = 1.5 and t = 2.5
