3 less than a number h is -12

Your equation would be h-3=-12
To solve this all you need to do is add 3 to both sides

h-3=-12
+3 +3
————
h=-9

So the equation is h-3=-12 and h would equal -9

I believe your equation would be ( H - 3 = -12 )

Answer:

Salena's got to the library first

Step-by-step explanation:

12½ miles = 25/2 miles

2½ miles = 5/2 miles

5¾ miles = 23/4 miles

114 miles = 114 miles

Salena's time of arrival =

if 5/2 miles : 5 minutes

then 25/2 miles : ?

25/2 ÷ 5/2. × 5

25/2 × 2/5 × 5

25 minutes

Justin 's time of arrival=

if 23/4 miles : 12 minutes

25/2 miles : ?

25/2 ÷ 23/4 ×12

25/2 × 4/23 ×12

26 minutes approximately

Brandon 's time of arrival=

if 114 miles : 258 minutes

25/2 miles : ?

25/2 ÷114 ×258

25/2 × 1/114×258

25 × 1/57 × 258

113 minutes approximately

Anyone know how to do area or volume? Any help will do! thanks

exis [7]

Answer:

Volume: x(x+6)(x+2) Area: $x^{2}$ + 8x +12

Step-by-step explanation:

Volume Explanation:

To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= $x^{3}$ + 8 $x^{2}$ + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.

Area:

To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= $x^{2} + 2x + 6x +12$ to get a final answer of $x^{2} +8x +12$ . This will be the formula when you find the area of the 2D figure in question.
