Equations : gather like terms then calculate.
Triangle A = 1/2 base X height
Prism V = L x W x H
do the maths yourself.

8-2x=15
-2x=7
x=-3.5
4x+16=28
4x=12
x=3
what is the area of a triangle that has an altitude of 5m and a base of 7m? IS IT A RIGHT TRIANGLE?
Assuming it is a right triangle:
A = 1/2 * b * h
A = 1/2 * 7 * 5
A = 17.5 square meters
Volume = 1/2 * b * h * L
V =1/2 * 5 * 10 *16
V = 300 cm cubed

For a triangle, area= 1/2 base X height
A=1/2*5*7= 17.5 (mtrs)^2 (square meters)
Prisim volume =
1/2XbaseXheight X length
=1/2 5*10*16= 300 cubic centimeters.

What are you doing your homework on here?
9-2x=15 - subtract 9 from both sides and divid by -2
4x+16=28 - subtract 16 from both sides, and devid by 4
area of a triangle is 1/2base x height
volume of a rectangular prism is length x width x height
do the math yourself

X=-3units & X=3units
area of triangle=17.5 m^2
vol. of rec.prism=800 cm^3

the third question the respond is one hundred twenty degreees. 900+1200+six hundred =2700 2700/900 = 3 so which you will say that 900 is a million/third of the circle, or one hundred twenty levels because of fact 360/3= one hundred twenty i think of the 2d one is 800 cubic centimeters V= L*W*H so sixteen*10*5 = 800
