Answer:
The perimeter of the first question is 62
If you draw it, you'll you'll see that it's a rectangle. The length of each side is calculated by adding the widths and heights as in the photo ( red ), and then adding them up. 13 + 18 + 13 + 18 = 62
You do the same with question 2, but this time the rectangle is smaller. (green in the photo)
So the perimeter is:
13 + 14 + 13 + 14 = 54
The answer to question 3 is (-15, -5) as drawn in the photo.
Answer:
The answer to x is x= −206
/31
Step-by-step explanation:
Simplify both sides of the equation.
34(x+6)=3x−2
(34)(x)+(34)(6)=3x+−2(Distribute)
34x+204=3x+−2
34x+204=3x−2
Subtract 3x from both sides.
34x+204−3x=3x−2−3x
31x+204=−2
Subtract 204 from both sides.
31x+204−204=−2−204
31x=−206
Divide both sides by 31.
31x
/31
= −206/
31
x= −206
/31
Answer: x= −206
/31
Answer:
21.21
Step-by-step explanation:
length of arc= 135°÷360×2×π×r
take π=22/7
radius=18/2=9
135°÷360×2×22/7×9
using calculator= 21.21
