Step-by-step explanation:
85÷4=21.25
12+6x was subtracted from the left but only 12 was subtracted from the right.
6x and 6 are not equal unless x=1
X=-11/15
Answer:
it is twice as long(10/12 inches longer
Step-by-step explanation:
1 4/6 make the 6 a 12 and the four a 8. 1= 12/12 so 8+12=20 so 20/12 and 20 is 10/12 more that 10/12 or twice as much.

Answer:
Area=36.66 cm^2
Step-by-step explanation:
First, you need the height.
Use the Pythagorean theorem:
hypotenuse^2=height^2+(1/2 base)^2
It's one-half base because it's an equilateral triangle.
1/2 base =4.6
(9.2)^2-4.6^2=height^2
84.64-21.16=height^2
height^2=63.48
height=7.97
Area=(1/2)(base)(height)
Area=(1/2)(9.2)(7.97)=36.66 cm^2
