The value of A is 4

4x2 – 20x + 3 = 0
-3 -3

4x2 - 20 x = - 3

Pull out common factor which is 4

4 ( x2 - 5x) = - 3

Answer:

The value of A is 4.

Step-by-step explanation:

Consider the provided quadratic equation.

$4x^2-20x+3=0$

Subtract 3 from both sides.

$4x^2-20x+3-3=-3$

$4x^2-20x=-3$

Now take 4 common from the left side of the above equation.

$4(x^2-5x)=-3$

Compare the above equation with $A(x^2 - 5x) = -3$

By the comparison it is clear the value of A is 4.

Hence, the value of A is 4.

Answer:

Area: $\frac{8}{15}$ feet²

Perimeter: $\frac{44}{15} =2 \frac{14}{15}$ feet

Step-by-step explanation:

The formula of finding the area of a rectangle or square is width multiplied by length.

The formula of find the perimeter of a rectangle or square is width+width+length+length

Area: $\frac{4}{5} *\frac{2}{3} = \frac{8}{15}$ feet²

Perimeter:

$\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =$

$\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\$

$\frac{44}{15} =2 \frac{14}{15}$

Rewrite in a form that does not use exponents

emmainna [20.7K]

Answer:

$\boxed{18}$

Step-by-step explanation:

One of the rules of logarithms is ...

log(a^b) = b·log(a)

So ...

$6\log_5{x^3}=6(3\log_5{x})=\bf{18}\log_5{x}$

HELLPPPP!!!

Kamila [148]

A + M = 40

M = 2A + 4

A + 2A + 4 = 40

3A = 40 - 4

3A = 36

A = 12 points

M = 40 - 12

m = 28 points

Please help functions

katrin2010 [14]

A function is an equation or graph where each x value only has one y value. In the first image you can use the vertical line test. Take your pencil and lay it on the paper vertically. Move it across the graph. Basically if an x value has multiple y value it is not a function. The first image is not a function because all x values past zero have multiple y values for each x value. In the second image it is not A because in A the x value of 2 has a y value of 1 and 8. It is not B because the 5 has a y value of 3 and 7. It’s is not D because of the 5 again. It is C because all x values are unique.

Hope that helps
