The rectangle below has an area of zº +82 + 15 square meters and a width of 2 + 3 meters.
Lelu [443]

Answer:

(x + 5) m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = (x² + 8x + 15) m²

Width (W) = (x + 3) m

Length (L) =?

The lenght of the rectangle can be obtained as follow:

A = L × W

x² + 8x + 15 = L (x + 3)

Divide both side by x + 3

L = x² + 8x + 15 / x + 3

L = (x + 5) m

Please attached photo for explanation.

Therefore, the length of the rectangle is: (x + 5) m

Let n (AUB)=32n(B)=16and n(ANB)9 find n (A)​
Lubov Fominskaja [6]

Answer:

32

Step-by-step explanation:

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

Given n(A)= ? we represent with x

n(B)= 16

n(A∪B) = 32

Substituting in equation 1 to get n(A)

32  = n(A) + 9 − 9

⇒n(A) = 32 − 0

n(A)  = 32

to confirm this we put the values into the formula below

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

32 =  32 + 9 - 9

Brett create a function of X with seven points each in a different location on the grid he graph sixth of the points as shown us
alina1380 [7]

Answer:

any point where x=3, 4, or 6.

Step-by-step explanation:

The thing that makes a function a function and not a relation is having only 1 y value per x value, which means if you draw a vertical line through a point, it should not intercept any other points. Basically, the main difference between a function and a relation is that a function can't have 2 points on top of each other.

Pick a point where x=3, 4, or 6. Those are the open spots on the grid with nothing above or below them. It doesn't matter which point you pick, as long as there is NOTHING directly above or below that point.

I hope you understood this solution. Happy mathing!
