Answer:21

Step-by-step explanation:

x=length

x(x-6)=315

x^2-6x=315

x^2-6x-315=0

(x-21)(x+15)

x=21, x=-15

x cannot be negative so the only answer is 21

Answer:

y = 3x + 4

Step-by-step explanation:

✔️First, find the slope using any two given pairs form the table, say (2, 10) and (5, 19):

Slope (m) = ∆y/∆x = (19 - 10) / (5 - 2) = 9/3

m = 3

✔️Find y-intercept (b) by substituting (x, y) = (2, 10) and m = 3 into y = mx + b

10 = 3(2) + b

10 = 6 + b

10 - 6 = b

4 = b

b = 4

✔️Write the equation by substituing m = 3 and b = 4 into y = mx + b

y = 3x + 4

What is 3x^4 + 5x^3 + x^2 - 5 divided by x + 2
Brilliant_brown [7]
Remember, there is a missing term which is crucial to solving this, and that is 0x.

Ima use synthetic division, because that's the quicker option here:

The zero of x+2 is -2...

-2 | 3 5 1 0 -5
-6 2 -6 12
_____________
3 -1 3 -6 7

(Sorry, I'm unsure how to fix the formatting, plus I'm new to this. The -6 and such on the second line should be below the 5 and following of the first line, and the 3 and such on the last line should be below the 3 and following on the first line, leaving a space between the 3 on the first and third line.)

So the answer is: A. 3x^3 - x^2 + 3x - 6 + 7/(x+2)
