3-4x+5=16-4x =>>kick 1. -4x to right side =>>
8=16-4x+4x=>> 8=16 that means question is wrong lol
Question should be 3+4x+5=2(8-2x) or 3-4x+5=2(8+2x)
Then the answer will be 8x=8 =>> x=1 :)
Answer:
d is the answer
Step-by-step explanation:
perimeter of rect = 2(7+3) = 20
perimeter of square = 4 a =20
a = 5
Answer:
tan(20) = 4 / x
tan(20)x = 4
x = 4 / tan(20)
<u>x = 10.99 units</u>
Step-by-step explanation:
Answer:
(y+1) = 3(x-1)
Step-by-step explanation: The key here is point slope form. Whenever you are given questions with a given point (y1, x1) and slope m just use this form, (y-y1)=m(x-x1)
Answer:
Percentage decrease in surface area =
Step-by-step explanation:
Given: A right circular cylinder has a radius of 6 inches and a height of 4 inches.
To find: percent change in surface area of the cylinder if height and radius are decreased by 10%
Solution:
Original radius of cylinder (r) = 6 inches
Original height of cylinder (h) = 4 inches
Original surface area of cylinder (a) =
New radius of cylinder (R) = inches
New height of cylinder (H) =
New surface area of cylinder (A) =
Decrease in surface area =
Percentage decrease in surface area =
