Answer:
4x^2
Step-by-step explanation:
This cannot be combined with the other variables because they are unlike terms
Answer:
x=61 -> Figure A
x=27 -> Figure B
x=12 -> Figure C
Step-by-step explanation:
<u>For A:</u>
<u>x=61</u> because the line going through the shape cuts in angle into 2 congruent angles
<u>For B:</u>
The corner adds up to 90 because it a rectangle, and rectangles only have right angles.
So: 2x+10+x-1=90
Solve.
3x+9=90
3x=81
<u>x=27</u>
<u>For C:</u>
The two given angles should add up to 90.
4x+10+2x+8=90
Solve.
6x+18=90
6x=72
<u>x=12</u>
Answer:
The area of CD is 17.71
Step-by-step explanation:
Radius of the disk = = 2.375 in
Since CD is in shape of circle So area of the circle is given by
Put the value of radius in above equation we get
A = 3.14 ×
A = 17.71
Therefore the area of CD is 17.71
Answer:
x = 15.97
Step-by-step explanation:
Answer:
1.x=15
2.<A=29
Step-by-step explanation:
(2x-1)+(3x+9)+(6x+7)=180
2x-1+3x+9+6x+7=180
11x+15=180
11x=180-15
11x=165
x=165/11
x=15
2.<A=2x-1
<A=2*15-1
<A=30-1
<A=29
