Step-by-step explanation:
Jessica planted a rosebush in her garden. The rosebush has a height of 30 cm. Each month the rosebush increases by 6 cm. Which equation can be used to determine the height of the plant in centimetres, y, after x months?
the rate of increase of the bush every month is 6 cm
Rate of increase of the bush in x months = 6x
because the bush increases every month, 6x would be added to 30cm
y = 6x + 30
If the bush decreased at a rate of 6cm every month, the equation would be y = 30 - 6x
Answer:
No triangle
Step-by-step explanation:
All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.

To solve this we are going to use a conversion factor. We know that 1 BTU per hour is approximately 778 foot-pounds of energy per hour, so our conversion factor will be:

.
Now we just need to multiply <span>4000 BTU by our conversion factor:
</span>

<span>
We can conclude that the furnace released </span><span>
3,112,000 foot pounds of energy in one hour.</span>
