Answer:
x=2
Step-by-step explanation:
first we will distribute out everything
-2x +5 +4x+ 9 = 3(6 +4x)- 12x
(multiply 3 to both 6 and 4x)
-2x +5 +4x+ 9= 18 +12x -12x
then combine like variables on both sides
(add -2x and 4x and add 5 and 9, for the other side add 12x and -12x)
2x+14= 18
then isolate x
2x=4
x=2
and substitute x for 2 to double check
-2(2)+5+4(2)+9=3(6+4(2))-12(2)
18=18
therefore 2 is correct
17. A rectangular prism has a length of 12 cm, a
height of 6/cm, and a width of 4 cm. Use the
formula SA = 2({w) + 2(wh) +2(ehy to find the
surface area of the rectangular prism.
Answer:
SA = 288 cm
Step-by-step explanation:
l = 12
w = 4
h = 6
SA = 2lw + 2wh + 2lh
SA = (2 x 12 x 4) + (2 x 4 x 6) + (2 x 12 x 6)
SA = 96 + 48 + 144
SA = 288

Can someone pls help me with this?
Answer:
the answer is d
Step-by-step explanation:
so for one do y-intercept has to be at (0,25) so we can eliminate answer choices B and C
the reason why it is not a is because a is moving out of constant rate of 25 when it needs to be moving at a constant rate like 10 D is the answer because it's moving at a constant rate of 10 and it has a y intercept of (0,25)

10) x = 118°
11) x = 145°
12) x = 40°
Step-by-step explanation:
9) 180-91 = 89
10) x = 118° because it is alternate interior to 118
11) x-30 = 115, x = 145
12) 4x-15 = 145, 4x = 160, x = 40

I have gotten 100% on the quiz. The answer is 4/5 square feet.
Step-by-step explanation:
The area of the rectangle with the given measurements is 4/5 square feet.
How to find the area of a rectangle?The area of a rectangle can be found by multiplying the 2 adjacent sides of the rectangle. In a rectangle with sides l and b, the area can be found by A = l*b.
The length and width of the rectangle are given. We can find the area of the rectangle as follows:
[tex]\text{Area} =2\frac{2}{5} (\frac{1}{3} ) \text{ft}^{2}[/tex]
= (12/5) * (1/3) square feet
= 4/5 square feet
