Answer:
12 and (-12)
Step-by-step explanation:
Solve for x.
x^2= 144
square root both sides and get,
x= 12
and
x= (-12)
remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.
Answer:
x = 12
x = -12
Step-by-step explanation:
Step 1: Take the square root of both sides.
[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]Therefore, x = 12 and x = -12 are the answers.

The circle graph shows the results of a survey. Of those surveyed, 10 said no. About how many people were surveyed?
Answers
Answer:
50 people
Step-by-step explanation:
so to solve this we can use cross multiplying:
first we know that 20% = 10 people and 80% = x people (we put x because we don't know how many people)
then we set it up:
[tex]\frac{10}{20}[/tex] = [tex]\frac{x}{80}[/tex]
= 20x = 800
= x = 40
now it asks how many people were surveyed in total so we add the 10 + 40 = 50
50 people were surveyed

The length of a rectangle is four times its width.
If the perimeter of the rectangle is 70 ft, find its length and width.
Answers
Let W represent width of rectangle
L=4W
2L+2W=70
Substitute 4W for L
2(4W)+2W=70
8W+2W=70
10W=70
Divide both sides by 10
W=7
Use equation from beginning
L=4(7)
L=28
Width is 7 ft, length is 28 ft
Check work
2(28)+2(7)=70
56+14=70
70=70

Answer:
a) 60° b) 50°
Step-by-step explanation:
The measurements of a triangles total angles is always equal to 180.
In question a), an Equilateral triangle is shown. Which means all the sides and angles are equal. So you divide 180 by 3, which equals 60.
In question b), an Isoceles triangle is shown. Which means two of the three sides and angles are equal. The other angle is already given: 80.
All you need to do now is subtract 80 from 180 and divide the diffrence by 2.
So, 180-80=100
100/2=50
S=50
Q=50
