Answer:
The surface area is 270in units squared
1.5(x + 4) - 3 = 3.5(x - 2)
We need to use the distributive property to simplify this.
1.5x + 6 - 3 = 3.5x - 7
<em><u>Subtract 1.5x from both sides</u></em>
6 - 3 = 2x - 7
<em><u>Simplify left side</u></em>
3 = 2x - 7
<em><u>Add 7 to both sides</u></em>
10 = 2x
<em><u>Divide both sides by 2</u></em>
x = 5
Answer:
d = all real numbers
Step-by-step explanation:
3(2d-4)-4d<2d+4
distribute
3*2d -3*4 - 4d < 2d+4
6d -12 -4d < 2d+4
combine like terms
2d -12 < 2d+4
subtract 2d from each side
2d -2d -12 < 2d-2d+4
-12 < 4
this is true always
so the inequality is true for all values of d
