Expression

1 answer:

4 0

The value of the expression is -24

This is because you distribute the -4 to both of the values in the parenthesis like this:
-4(7) + -4(-1)
This can be simplified to:
-28 + 4
Which equals -24
Hope this helps!

What are the square roots of 64/144 ?

nordsb [41]

Answer: third option

Step-by-step explanation:

To solve the problem you must apply the proccedure shown below:

- Descompose the numerator and the denominator of the given fraction into its prime numbers:

$64=2*2*2*2*2*2\\144=2*2*2*2*3*3$

Then you can rewrite:

$64=2^6\\144=2^4*3^2$

Then:

$\±\sqrt{\frac{{2^6}}{{2^4*3^2}}}=\±\frac{2^3}{2^2*3}=\±\frac{8}{4*3}=\±\frac{8}{12}$

Therefore, the answer is: $-\frac{8}{12}\ and\ \frac{8}{12}$

The function shown in the graph is

pshichka [43]

Answer:

Linear function

y = 2x - 1

Step-by-step explanation:

This is a linear function because the line is straight, having no curved.

The equation for a linear graph is y=mx + b.

x and y represent points on he graph.

"m" represents the slope of the graph. Reading from left to right, if a positive slope, then the graph continues upward. If negative, then it's a graph down downwards.

"b" represents the y-intercept, when the graph hits the y-axis. It's also the initial value.

In the photo, we can see the y-intercept is (0, -1).

Slope is calculated by rise over run. Choose two random points on the graph. Count the "rise", or how many vertical units are between the points. If the point on the right is lower than the point on the left, the rise is negative. Count the "run", which is the number of horizontal units between the points.

For the point (0, -1) and (3, 5).

m = rise/run

m = 6/3

m = 2

Substitute m=2 and b= -1 into the equation of a line.

y = 2x - 1

Tom wants new carpeting for his bedroom. His room is a 999 meters by 777 meters rectangle. How much carpeting does he need to bu

fomenos

Answer:

777,223 meters squared

Step-by-step explanation:

To find the amount of carpeting, we must find the area of the floor of Tom's bedroom.

To find area, we multiply the length and width of the rectangle.

999 x 777 = 776,223

Remember, when we find the area, we must give the answer in square units.

Our final answer is 777,223 meters squared
