3 0

Answer:

x = 15, 72 degrees

Step-by-step explanation:

4x + 12 + 108 = 180

4x + 120 = 180

4x (+ 120 - 120) = 180 - 120

4x = 60

4x/4 = 60/4

x = 15

4x + 12

4(15) + 12

60 + 12

72 degrees

<u><em>Answer: x<-6 *The answer should be the negative sign.*</em></u>

Step-by-step explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

subtract 5 both sides of an equation.

5-2x-5>17-5

simplify.

-2x>12

multiply by -1 both sides of an equation.

(-2x)(-1)<12(-1)

simplify.

2x<-12

divide by 2 both sides of an equation.

2x/2<-12/2

-12/2=-6

12/2=6

6*2=12

12/6=2

x<-6

Hope this helps!

Thanks!

Have a great day!

The volume of the cuboid is 120 cm<br> Find x<br> 5 cm<br> 4 cm
belka [17]

Answer:

6cm

Step-by-step explanation:

Volume of cuboid = length × breadth × height

Length = x

Breadth = 4cm

Height = 5cm

Volume = 120cm³

Volume = 4 × 5 × x

120 = 20x

Divide both sides by 20

20x/20 = 120/20

x = 6cm
