Answer:

y = 6x - 17 \\ y =  - 4x + 23 \\ then \\ 6 x - 17 =  - 4x + 23 \\ 10x = 40 \\ x = 4 \\ y = 7

PLEASE ANSWER! When a trinomial is factored as (x+m)(x+n), what is the sum of m and n?
Temka [501]
C. The coefficient of the x-term of the trinomial

Again, here's your reason:
(x+m)(x+n)
x^2 +xm+nx +mn
x^2 + x (m+n) + mn


As you can clearly see that the sum of m and n equal the coefficient of x term so, the correct option is C.

Michelle has a maximum of 4500 milliliters  of water for her plants today. Each basil plant requires 350 of water, and each fenn
anyanavicka [17]

The inequality becomes :

350B+525F≤4500

Explanation:

Let the number of basil plants be represented by = B

Let the number of fennel plants be represented by = F

As each basil plant needs 350 ml of water, so B basil plants will need 350*B = 350B ml of water

Similarly, each fennel plant needs 525 ml of water so F fennel plants will need 525*F = 525F ml of water.

And both the plants need to be watered with a maximum of 4500 ml of water.

So inequality becomes: 350B+525F≤4500

A rectangular prism has a base area 56 ft.² and a volume of 840 ft.³ the length of the base is longer than the width if the sum
suter [353]

Answer:

The length of the base in feet is 8 ft.

Step-by-step explanation:

The volume V of the rectangular prism is given by

V = l × w × h

But Area, A = l × w

∴ V = A × h

Where A is the base area and h is the height

From the question

A = 56 ft.²  and V = 840 ft.³

∴ 840 ft.³ = 56 ft.² × h

840 ft.³ / 56 ft.² = h

15 ft. = h

∴ h = 15 ft.

Hence, the height of the rectangular prism is 15 ft.

Also, from the question

the sum of the length and the width of the base is equal to the height

i.e l + w = h

where l is the length of the base and w is the width of the base

Then, l + w = 15 ------ (1)

Also, A = l × w

Then, 56 = l × w ------- (2)

From equation (1)

l + w = 15

Then, w = 15 - l ------- (3)

Substitute this into equation (2)

56 = l × w

56 = l × (15-l)

56 = 15l - l²

Then,

l²- 15l + 56 = 0

l² -8l -7l + 56 = 0

l(l - 8) -7(l - 8) = 0

(l - 7)(l - 8) = 0

l - 7 = 0 OR l - 8 = 0

∴ l = 7 OR l = 8

Substitute the values of l into equation (3)

w = 15 - l

when l = 7

w = 15 - 7

w = 8

and when l = 8

w = 15 - 8

w = 7

From the question, the length of the base is longer than the width

∴ l = 8 and w = 7

Hence, the length of the base in feet is 8 ft.
