Answer:

Factors are (2a+b) and (5x-4y)

Option D is correct.

Step-by-step explanation:

Given: 10ax+5bx-8ay-4by

Here we are four term to factor it.

First we make two group and factor each group.

(10ax+5bx) + (-8ay-4by)

\text{Group 1: }10ax+5bx

Taking 5x common from both term

10ax+5bx\Rightarrow 5x(2a+b)

\text{Group 2: }-8ay-4by

Taking -4y common from both term

-8ay-4by\Rightarrow -4y(2a+b)

Factor is:

\Rightarrow 5x(2a+b)-4y(2a+b)

\Rightarrow (2a+b)(5x-4y)

Hence, Factors are (2a+b) and (5x-4y)

Answer:

Step-by-step explanation:

Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2

First parallelogram has h=4cm (from first triangle) and a=5.7cm

P2=a*h=22.8cm^2

Big triangle has h=4 and a=5.7+4=9.7

P3=a*h/2=9.7*4/2=19.4

And 4th triangle has the same are lik the first one, P4=8.

P=8+22.8+19.4+8=58.2cm^2

The equation of the line in this graph is<br>y= ____ x+____ .<br>​
Alexxx [7]
The equation of the line in this graph is y = 3/2x + 3.

Explanation:

In slope intercept form equations, the initial value is where everything begins. In this equation, that would be at the point (0,3). From there, because it is going up toward the right side, there is a positive slope. The formula for slope is rise over run, so to get our slope, we have to go up 3 units and over 2 units.

If 15% of an item is $18.00 what was the original price?
larisa [96]
<span>from the whole price,
15% of this price is equal to $18.00.
therefore if 15 % equals $18.00
                                                                     
then 100% is the original price therefore 100 % = 18.00 / 15 % x 100% = $120 therefore original price = $120</span>
