10 + 4 x 5 = 30 (10 + 4) x 5 = 70
10x + 4 = 3x + 9Subtract 3x from each side of the equation:7x + 4 = 9Subtract 4 from each side:7x = 5Divide each side by 7:x =5/7
-50
It is a quadratic expression that can be multiplied out to: x^2 +6x+8
(x + 4) + (x + 5) = 2x + 9
x + 5 + 4 = x + 9
8 x 3 + 5 = 29
5+3=8x4=32-8=24+2=26x7=182 If order of operation is followed then the mutiplication has to be done first. Then you add/subract the rest of the numbers from left to right. 5 + 3 x 4 - 8 + 2 x 7 = X (3x4) (2x7) 5 + 12 - 8 + 14 = X X=23
Negative five (-5) multiplied by negative four (-4) is positive twenty (20) or (-5) x x(-4) = +20
If you mean: x+4(x+5) then it is 5x+20
16 X 6 + 4 = 100
119.96 + 4 + 3 + 576 + 4 + 3 + 4.5 = 714.46
