Answer:649
Step-by-step explanation:my because I want points sorry lol
First we would find the area of the entire thing,
A=1/2(base)(height)
so A = 1/2(5)(12) = 30 mm^2
next we find the area of the smaller triangle,
A = 1/2(4)(3) = 6 mm^2
Then we subtract the area of the smaller triangle from the area of the larger one
30-6 = 24 mm^2
First you must distribute the 2 to the numbers inside the parentheses, which would be 1 and -x...
(2 * 1) + (2 * -x) > 2x
2 + (-2x) > 2x
2 - 2x >2x
Add 2x to both sides (what you do on one side you must do to the other). Since 2x is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.
2 - 2x + 2x > 2x + 2x
2 + 0 > 4x
2 > 4x
Next divide 4 to both sides to finish isolating x. Since 4 is being multiplied by x, division (the opposite of multiplication) will cancel 4 out (in this case it will make 4 one) from the right side and bring it over to the left side.
2/4 > 4x / 4
1/2 > x
or
x < 1/2
Hope this helped!

Answer:
80 meters :) lol
Step-by-step explanation:
Remember you can do anything to an equation as long as you do it to both sides
x/5-12=48
add 12 to both sides
x/5+12-12=48+12
x/5+0=60
x/5=60
multiply bot sides by 5/1
5x/5=60 times 5
x times 5/5=300
x times 1=300
x=300
