Answer:
5
Step-by-step explanation
becasue 2x0=0 and 1x0=0
and when you add 5 to 0 you get five
24 divided by 6( the amount of sides) is 4. The square root of 4 is 2 so each side is 2 cm. 2 cm tripled is 6 cm. 6 times 6 is 36 ( that is the surface area of one face). 36 times 6 (the number of faces) is 216 so the answer is 216 cm squared.
y=-5x-44
Step-by-step explanation:
5x+y=13 passes through (15,31)
rearrange the equation to y=mx+c
5x+y=13
y=-5x+13
substitute the points (15,31)
y=5x+c
31=5(15)+c
31=75+c
-44=c
y=-5x-44
Can be written as 5x+y=-44
-10 ≥ 2x + 14
-24 ≥ 2x [subtract 14 from both sides]
2x ≤ -24 [read right to left]
x ≤ -12 [divide both sides by 2]
Check:
Let x = -13 (It is ≥ -12)
Is this true: -10 ≥ 2(-13) + 14 ?
-10 ≥ -26 + 14 ?
-10 ≥ -14 ?yes
Let x = -11 (it is not ≥ -12)
Is this false:: -10 ≥ 2(-11) + 14 ?
-10 ≥ -22 + 14 ?
-10 ≥ -8 ?yes
