Answer:
This is true because the + and the - will turn into a negative, therefore it will stay zero
Step-by-step explanation:
+ (-x) = -x, NOT +x
Add them together and then divide by the number of numbers
like this:
joe had 7 beans
eric had 5
julie had 2
add them
you get 14
now divide by 3
4.6 with a bunch of 6
Answer:
x = 18 units.
Area of triangle = 156 units^2.
Step-by-step explanation:
Area of the rectangle = 4(2x + 3) and the area of the triangle = 1/2*6*(3x - 2).
These are equal, so:
4(2x + 3) = 1/2*6*(3x - 2)
8x + 12 = 9x - 6
12 + 6 = 9x - 8x
x = 18.
Area of triangle = 1/2 * 6 * (3(18) - 2)
= 3 * 52
= 156 units^2.
