Area = Length x Width

You can not express area as a sum.

Finding the area only involves multiplication Perimeter calculations can use sum and product since you add the sides some of which are the same you can use both methods EXAMPLE IN A SQUARE ALL SIDES ARE THE SAME SO YOU CAN USE ADDITION S+S+S=S+S= 4S OR 4 (S)= 4S

How many solutions does have 3x-6=3(x-2)<br>

Anarel [89]

Answer:

Infinite.

Step-by-step explanation:

$3x-6=3\left(x-2\right)$

Expand:

$3x-6=3x-6$

Add 6 to both sides:

$3x-6+6=3x-6+6$

$3x=3x$

Subtract 3x from both sides:

$3x-3x=3x-3x$

$0=0$

No matter what x is, it doesn't affect the answer. Thus, the equation is true for all values of x.

Let f(x) = x + 8 and g(x) = x2 − 6x − 7. find f(g(2)). −7 −3 10 33 open study

Ray Of Light [21]

F(g(2))

g(x) = x^2 - 6x - 7
g(2) = 2^2 - 6(2) - 7
g(2) = 4 - 12 - 7
g(2) = -15

f(x) = x + 8
f(g(2) = f(-15) = -15 + 8 = -7 <==

ur answer is -7

The area of a triangle is taken by multiplying the length of the base times the height then dividing by 2.
l = 14cm
h = 8cm
A = $\frac{l * h}{2}$
A = $\frac{14 * 8}{2}$
A = $\frac{112}{2}$
A = 56 $cm^{2}$

Solve the linear system of equations using addition. Graph the equations to verify your solution. required.

zhenek [66]

<h3>Answer:</h3>

infinite solutions

<h3>Step-by-step explanation:</h3>

Add the two equations.

... (-4x) + (y) = (y +3) +(-4x -3)

Add 4x -y to both sides.

... -4x +y +4x -y = -4x +y +4x -y

... 0 = 0 . . . . . true for all values of x (or y)

Both equations describe the same line.

_____

The graph shows the first equation as a red line. The second equation is shown using a "blue dot" texture, so you can see it overlays the red line.
