Answer:
10s²-6s+9
Step-by-step explanation:
C = -3 + 5s²
B = -2s + 5
2(-3 + 5s²) = -6 + 10s²
3(-2s + 5) = -6s + 15
10s² - 6s + 9
Answer:
A 4/81
Step-by-step explanation:
(2/9)² is the same as 2/9×2/9, which is 4/81.
Given:
The dimensions of a rectangle are
and
.
To find:
The expression that represents the area of the rectangle in simplest terms.
Solution:
Area of a rectangle is:

The dimensions of a rectangle are
and
. So, the area of the given rectangle is:




Therefore, the correct option is F, i.e.,
.
Answer:
I think it's the 3rd one
Step-by-step explanation:
because it makes sense
Probability of an event =
(number of ways the event can happen) / (total number of possible outcomes) .
Well, the total number of possible outcomes is easy. It's
(6 possibilities for the first cube) x (6 possibilities for the 2nd cube)
= 36 total possible ways for two cubes to roll.
Now, how many of those possibilities show either 4 or 7 ?
Well, here's how a 4 can come up:
1 . . . 3
2 . . . 2
3 . . . 1
and here's how a 7 can come up:
1 . . . 6
2 . . . 5
3 . . . 4
4 . . . 3
5 . . . 2
6 . . . 1 .
So there are 9 ways all together for Lenny to be successful.
The probability is (9/36) .
That's 1/4 , or 25% .
