Answer:
273
Step-by-step explanation:
base (l times w) times height
Isolate "x" onto one side:
5/3 * (6x+3) < 2x - 7
5(6x+3) < 3(2x-7)
30x + 15 < 6x - 21
24x < -36
x < -1.5
Answer:
Surface area is 72
The surface area unit is square centimeters, or 
Hope this helps!
4x - 3y - 7 = 0
-3y = -4x + 7
y = 4/3x - 7/3....slope here is 4/3
A. a parallel line will have the same slope
y = mx + b
slope(m) = 4/3
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = 4/3(-2) + b
1 = -8/3 + b
1 + 8/3 = b
3/3 + 8/3 = b
11/3 = b
so ur parallel line is : y = 4/3x + 11/3
B. A perpendicular line will have a negative reciprocal slope. To get the negative reciprocal of a number, u flip the number and change the sign. So our perpendicular line will need a slope of -3/4
y = mx + b
slope(m) = -3/4
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = -3/4(-2) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
so ur perpendicular equation is : y = -3/4x - 1/2
By similarity theorem, I will send you a picture when I'm done.
I hope that explains everything for you the value of x is 18 and I worked it out step by step for you so you would understand
