Answer:

constant = -12

Step-by-step explanation:

Let the given equation be

2x² + 8x - 12 = 0 --------(1)

Here B² =(2√2)^2 = 8

Add 8 in both sides of (1)

Step1 : 2x² + 8x + 4 = 12 + 4

Step 2: x² + 4x + 4 = 16

step 3 : x² + 4x + 4 - 16 = 0

Step 4: x² + 4x - 12 = 0 ---(4)

From the (4) we get constant = -12

In a set of five consecutive integers, the smallest integer is more than $\frac23$ the largest. What is the smallest possible va

Goryan [66]

Answer:

Step-by-step explanation:

Let x represent the middle integer. Then the smallest is x-2 and the largest is x+2. Your requirement is that ...

(x-2)/(x+2) > 2/3

3x -6 > 2x +4 . . . . cross multiply

x > 10 . . . . . . . . . . .add 6-2x

The smallest integer satisfying this requirement is x=11. The sum of the 5 integers is 5x = 55.

The smallest sum is 55.

Which equation represents the polar form of x² + (y + 4)² = 16?

Paraphin [41]

$x^2+y^2=r^2\hspace{5em}x=r\cos(\theta )\hspace{5em}y=r\sin(\theta ) \\\\[-0.35em] ~\dotfill\\\\ x^2+(y+4)^2=16\implies x^2+\stackrel{binomial~expansion}{y^2+8y+16}=16 \\\\\\ \underset{x^2+y^2}{r^2} + 8(~\underset{8y}{r\sin(\theta )}~)=16-16\implies r^2+8r\sin(\theta)=0 \\\\\\ r^2=-8r\sin(\theta )\implies \cfrac{r^2}{r}=-8\sin(\theta )\implies r=-8\sin(\theta )$

NEED TO KNOW ASAP PLEASE HELP

AnnyKZ [126]

Answer:

You are <em>squaring x and -5 on the first equation</em>, and on the second equation you are <em>just squaring x and subtracting 5.</em>

Step-by-step explanation:

And since on the first equation x and -5 are in parenthesis that means that the square goes to both of them.

And the second one there is no parenthesis so the square only goes to the x.

I hope this helps you.
