Answer:
x=5.5
Step-by-step explanation:
Perimeter of ABCD=85
The perimeter is everything around the outside added together.
Form an equation:
3x+4+4x+6x-11+5x-7=85
Collect the like terms:
Like terms are terms that have the same powers and coefficient.
3x+4x+6x+5x=18x
4-11-7= -14
Put it back into an equation:
18x-14=85
Do inverse operations to find out what x is:
85+14=99
18x=99
99÷18=5.5 (we divide because, in algebra, when a number is next to a letter, it means times and as we want the inverse, you would have to divide)
x=5.5
Hope this helps :)
Answer:
1177.5 inches
Step-by-step explanation:
Volume of a cylinder =
, where h is the height
Radius = 10/2 = 5 radius is half the diameter
Height = 3*5 = 15 height is 3 times the radius
V = 3.14 * (5^2) * (15)
= 3.14 *25 * 15
= 1177.5
Hi!
the answer for 16 - 23 is -7
You would have to change that 5% into 0.05 and multiple it by 2 you get 0.1.Now,multiple 0.1 by 20000 and you get 2000.
Answer:
Second option: -3x^2
Step-by-step explanation:
A is the product of -x and 3x, then:
A=(-x)(3x)→A=-3x^2
