h(x) = 5 - 9x
h(8) = 5 - 9×8 ( putting value x = 8)
h(8) = 5 - 72
h(8) = -67
Answer is -67.
Ken grew .425 of an inch more than Sang
2/5+3/8= 31/40 therefore he still has 9/40 to go.
to get this you multiply the two denominators together
5x8=40 which is your denominator
then you cross multiply the two numerators
2x8=16
3x5=15
to get the final
15/40+16/40=31/40
and you are left with 9/40
The surface area of a rectangular prism needs an formula.
For a rectangular prism you have to understand some about the shape.
It is a 3D shape consisting of 6 sides
all are rectangles
to determine the area of one rectangle is the base multiplied by the height or in this case length times with.
but you also need to account for all sides and the height.
so the Surface area formula would be like

this accounts for 3 of the sides of the rectangular prism.
the top,bottom,and side.
so to get the surface area of a rectangle prism you must mutiply each side by 2 to account for all sides of the rectangular prism.
so the surface area formula for a rectangular prism is

I won't solve it for you but just plug in your values for l,w,and h into that formula and you will get your answer in metres squared or m
An inequality may be used to model the given situation. The phrase, "no more than" implies "less than or equal to". Therefore, the inequality is:
15 ≤ t / 5
Solving the inequality of t, we get:
t ≥ 75
This means that the number t is at least 75 (the phrase at least implies greater than or equal to)
Hope this helps!
