Answer:

=14x² −3x −1

Step-by-step explanation:

simplifying step-by-step.

9x2+5x2+5x−3−(8x−2)

Distribute the Negative Sign:

=9x2+5x2+5x−3+−1(8x−2)

=9x2+5x2+5x+−3+−1(8x)+(−1)(−2)

=9x2+5x2+5x+−3+−8x+2

Combine Like Terms:

=9x2+5x2+5x+−3+−8x+2

=(9x2+5x2)+(5x+−8x)+(−3+2)

=14x2+−3x+−1

Answer:

=14x2−3x−1

Answer;

X = 18: AD = 18

Step-by-step explanation:

Here, we want to find the measure of AD

From the given image;

AB = x + 3

AD = x

AC = 24 + 4 = 28

AE = 24

Substituting these values

we have ;

(x + 3)/x = 28/24

24(x + 3) = 28x

24x + 72 = 28x

28x - 24x = 72

4x = 72

x = 72/4

x =18

Pachacha [2.7K]

Answer:

B. i and iii

Step-by-step explanation:

There are mistakes in your question. But I solve this problem using the average mean of 15 because that is what is contained in the solution

Hypothesis

H0: u <= 15

H1: u > 15

Mean of x = 16.6

S = 2.22

Test statistic used is t test

16.6 - 15 / 2.22/√24

= 3.531

We find the critical value

Degree of freedom = 24-1 = 23

This is a one tailed test

Critical value = 1.714

We find p value using Ms excel T distribution function

= 0.000894

To make the decision

3.531 > 1.714 so we conclude that

I.) Reject null hypothesis

Iii) conclude an average if more than 15 hours is volunteered per month. So no need to institute the program.

The answer option Is B

Select all of the equations that represent linear relationships.
ad-work [718]
There are linear relationships so long as the power of x is 1 when power of y is 1 / power of x is not 2 and above when power of y is 1. This is assuming you plot the vertical axis as y-axis and the horizontal axis as the x-axis.

So using this concept, the equation with linear relationships are:
1, 3, 4, and 5.

Hope this helps! :)

navik [9.2K]

Answer:

d= 12.50 miles

Step-by-step explanation:

Kinematic equation of uniform motion (constant speed) :

v= d/t  Formula (1)

v: velocity in miles per hour (mph)

d: distance in miles

t: time in hours

Data

v= 50 mph

t= 0.25 hours

Problem development

We replace data in formula (1)

50 mph=d/0.25 hour

50 \frac{miles}{hour} = \frac{d}{0.25 hour}

d= 50\frac{miles}{hour} *0.25 hour

d= 12.5 miles

d= 12.50 miles

Rudik [331]

Answer:

a^3b^4

Step-by-step explanation:

You have 3 a's, so that would be

a^{3}

and you have 4 b's so that would be

b^4

so putting it together gives you

a^3b^4
