Answer:

10 tomato plants and

15 rose plants

Step-by-step explanation:

Let t be the no. of tomato plants,

And r the no. of rose plants

t + r = 25

t + 2r = 40

t = 25 - r

25 - r + 2r = 40

r = 15

t = 25 - 15

t = 10

The Johnsons’ new swimming pool measures 3x^2-2x+1 ft in length and x+2 ft in width. What is the area of the new swimming pool,

Usimov [2.4K]

Answer:

$3x^3 + 4x^2 -3x + 2$

Step-by-step explanation:

The area of the swimming pool will be equal to $length * width$ .

We know that the length is $3x^2-2x+1$ and the width is $x+2$ .

Therefore we can substitute those into the equation:

$(3x^2-2x+1)(x+2)\\$

Then, we expand the brackets using a grid (attached).

After this, we collect like terms to find the final answer:

$3x^3+6x^2-2x^2-4x+x+2\\3x^3 + 4x^2 -3x + 2$

Our final answer is: $3x^3 + 4x^2 -3x + 2$

In a certain Algebra 2 class of 29 students, 5 of them play basketball and 16 of them play baseball. There are 10 students who p

kkurt [141]

ANSWER
$P(both\:sports)= \frac{2}{29}$

EXPLANATION
Let the number who plays both games be
$x$
Then those who play only basketball
$= 5 - x$

and those who play only baseball
$= 16 - x$

We were given that 10 students play neither sports.

We can then write the following equation,

$(5 - x) + x + (16 - x) + 10 = 29$

This implies that,

$- x + x - x = 29 - 5 - 16 - 10$

This simplifies to,

$- x = - 2$

This gives us,

$x = 2$

Therefore the number of students play both basketball and baseball is 2.

The probability that a student chosen from the class plays both basketball and baseball ball

$= \frac{2}{29}$
