Paul creates the diagram to help him factor 4x2 + x – 5 by using double grouping. His diagram is incomplete. Which terms should Paul write in squares M1 and M2?

a) 5x and −4x
b) –5x and 4x
c) –2x and 10x
d) 2x and −10x

5x and -4x

Step-by-step explanation:

Because Paul is looking for M1 and M2 in order to get a total that is +x and a product that is equal to -20x^2, we can see that 5x and -4x help Paul get the products he wants.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
