Answer:
x = 3 , X = -3
In x 2 = 9 , you need to get rid of the power of 2 in order to isolate just x This involves finding the square root. √ x 2 = x However there are 2 possible answers to a square root, a positive or a negative answer. x = ± √ 9 x = ± 3
Point B.
The square root of 15 is 3.8.
Point B refers to the answer of the problem.
Therefore, it’s point B, hope this helps.
A) area = length x width = 12 x 6 = 72 sq.cm
B) area = 1/2x base x height = 1/2 x 3 x 6 = 9 sq.cm
C) same as B= 9 sq. Cm
D) subtract area of both triangles from area of rectangle:
72 - 9 -9 = 54 sq. Cm
Well let's make x=#of gallons pumped in the smaller tank, so g+x=25
so x=25-g.
The question is a little confusing with the given info tho, but I'm assuming you mean this.
