Answer: 18x^4 - 5x^3 + x^2 - 4
Step-by-step explanation:
We need to add like terms.
-10 and 6 are like terms
-10 + 6 = - 4
-3x^3 and -2^3 are like terms
-3x^3 + -2^3 = -5x^3
There are no other like terms.
18x^4 - 5x^3 + x^2 - 4
Answer:
Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.
Step-by-step explanation:
Jimmy reads a page, on average, every 20 seconds.
5 × 60 = 300
300/15 = 20
therefore, one page every 20 seconds
1:20
Carlo reads a page, on average, every 30 seconds.
6 × 60 = 360
360/12 = 30
therefore, one page every 30 seconds
1:30

Answer:
Option C. 
Step-by-step explanation:
we know that
The volume of the triangular prism is equal to
where
B is the area of the triangular base
H is the height of the prism
Convert 9 ft to yd
Remember that
1 ft=1/3 yd
9 ft=9*(1/3)=3 yd
<em>Find the area of the base B</em>
we have
substitute the values in the formula
Answer:
if the area of the rectangle is the same then the height of the triangle would be double that of the rectangle
Step-by-step explanation:
this is because the formula for working out the area of a triangle is base multiplied by height divided by 2 and so will need to be double to overcome the dividing factor.
