Answer:
She can play for 24 minutes and 30 seconds
Step-by-step explanation:
Let minute be represented by X
she is hit already 41 times
She is hit 10 times a minute meaning in X minutes she is hit 10X
41 + 10X ≤ 286
10X ≤ 286 -41
10X ≤ 245
X≤24.5
She can play for 24 minutes and 30 seconds

Answer:
Option D.
Step-by-step explanation:
The given expression is (5r + 2)(3r minus 4)
Convert this expression into an algebraic expression.
(5r + 2)(3r - 4)
By distribution law,
= 5r(3r - 4) + 2(3r - 4)
= 15r² - 20r + 6r - 8
= 15r² - 14r - 8
Now convert the algebraic expression into the language form.
15r squared minus 14r minus 8
Therefore, option D is the answer.
