(5a - b)(5a + 8b)
5a(5a + 8b) - b(5a + 8b)
5a(5a) + 5a(8b) - b(5a) - b(8b)
25a² + 40ab - 5ab - 8b²
25a² + 35ab - 8b²

(5a-b)(5a+8b)=(5a*5a)+(5a*8b)+(-b*5a)+(-b*8b)=25a^2+40ab-5ab-8b^2=25a^2+25ab-8b^2

VikaD [51]
For this case, the first thing to do is to calculate the time you were watching the game.
 We have then:
 2:00 - 1:45 = 15 minutes
 Then, the amount of degrees is given by:
 (15/60) * (360) = 90 degrees
 Answer:

On a piece of paper, graph y < 3/4 x+2 Then determine which answer matches the graph drew.
OleMash [197]

Step-by-step explanation:

Given inequality is y.

To graph that inequality, first we need to graph the line y=\frac{3}{4}x+2. Then shade it for the inequality symbol <.

Graphing line can be done using two points.

plug x=0 into y=\frac{3}{4}x+2, we get:

y=\frac{3}{4}*0+2=2

Hence first point is (0,2)

Similarly plug any random number for x say x=4, we get:

y=\frac{3}{4}*4+2=5

Hence first point is (4,5).

Now we just need to graph both points and join them by a dotted line. because we have < not <=.

Next part is to test for shading.

Which can be done using any test point which is not on the given line. Say (0,0)

plug x=0,y=0 into y.

0

0

0<2

which is true, hence shading will be in direction of test point (0,0).

Hence final answer will be the choice which looks like the graph attached below;
