What are the demensions of a rectangle if the perimiter is 20 and the area is 24

Advocard [28]

Answer:

I simply listed the factors of 24, and tested which ones worked in this equation: P = 2a + 2b.

So the factors listed were:

24 x 1

12 x 2

8 x 3

6 x 4

After testing each one of these, 6 and 4 had worked for me.

P = 2(6) + 2(4)

P = 12 + 8

P = 20

Therefore, the dimensions of this rectangle are 6 and 4.

M=2 , (6,6) <br> Write the equation in the form Ax+By=C.

Karolina [17]

Since m= slope =2, slope is rise/run, or (y2-y1)/(x2-x1), we'll make the point (6,6) = (x1,y1)
In point-slope form, y-y1 = m (x-x1) -->
y-6 = 2 (x-6)
y-6 = 2x-12
+6 = +6
y = 2x-6
-2x = -2x
-2x+y = -6

Please help me solve these are quadratic equations: I

julia-pushkina [17]

Answer:

$\boxed {\boxed {\sf a= 3, b=7, c=2}}$

$\boxed {\boxed {\sf Y-intercept = c }}$

$\boxed {\boxed {\sf Minimum}}$

Step-by-step explanation:

a. a, b, c

Quadratic equations in standard form are written as:

$f(x)= ax^2+bx+c$

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.

$f(x)= 3x^2+7x+2$

$a=3 \\b=7 \\c=2$

b. Y-intercept

The y-intercept for a quadratic is c.

You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).

$f(0)= 3(0)^2+7(0)+2$

$f(0)=3(0)+7(0)+2\\f(0)= 0+0+2\\f(0)=2$

We know that c=2, so the y-intercept is c.

c. Maximum/minimum

The entire quadratic is positive, so the quadratic opens up and has a minimum.
