5x + 3 = -2
5x = -2 -3
5x = -5
x = -1
that is simple case dr.....
(150/360)*36
150/10
15
that is a simple question....
5 - (-1)
5 + 1
6
(2^x )* (3^x) = 216
(2.3)^x = 216
6^x = 216
6^x = 6^3
x = 3//
2x(x^2 + 5)
2x^3 +10x
i think this answer is correct.
-11y + (-9x) + (-2x)
-11y -9x -2x
-11y -11x
-11(y+x)//
That is a simply answer.
y is a variable . so i think we can that variable equal to another formulas
5 + 2*5+4*5+-4*5+-2
5+10+20-20-2
5+10-2
15-2
13//
I think X meaning is *(mutipy). so i solve this question in easily.
4+7
11//
that is the answer. that's a simple question.
(-20)-(12)
=-20 - 12
= -32//
