You would add them together if it’s on a number line bc u have to go 5 to get to 0 then another 13 so 13+5=18
Answer:
325 mph and 420 mph
Step-by-step explanation:
If the speed of the slower plane is x, then the speed of the faster plane is x + 95.
The distance traveled by the slower plane is 3x.
The distance traveled by the faster plane is 3(x + 95).
The total distance is 2235 miles.
3x + 3(x + 95) = 2235
3x + 3x + 285 = 2235
6x = 1950
x = 325
x + 95 = 420
The speed of the planes is 325 mph and 420 mph.
Answer:
Square and cube numbers are special sequences of numbers that are linked to the property of the shape they are named after. A square number relates to the area of a square. A cube number relates to the volume of a cube.
Step-by-step explanation:
1.)combine like terms: 12-2x=10x 3-10=-7
10x-7
As we know the volume of a prism is the product of height and base are
H(x)= height, A(x)= Base area
Thus,
When volume = height(base area )
V(x)= A(x) · H(x)
= (x²-2)(5)
= 5(x² -2)
