The solution is p = 10 and p = -2
To solve for both p's, you have to find two factors of -20 that when multiplied, equal -20, but when added equal -8 (2 and -10).Since the -20 is negative, one of the numbers has to be negative.
Now that you have the 2 numbers, you solve for "p".
P - 10 = 0. Add 10 to both sides, P = 10
P + 2 = 0. Subtract 2 on both sides. P= -2.

Answer:
c) 30
Step-by-step explanation:
since the lines are parallel, 75° = 2x + 15°
this is because when two parallels lines are intersected by the same line, all respective angles are equal. Also, opposite angles on a line are equal too.
So now that u have 75 = 2x + 15, just solve for x by simplifying:
75 = 2x + 15
60 = 2x
30 = x
so the answer is c) 30

Answer:
GOOD!
Step-by-step explanation:
Length = 60; Width = 36
The formula for Perimeter is P = 2L + 2W
Where L = length; W = width
192 = 2L + 2W
= 2(5x) + 2(3x)
= 10x + 6x
= 16x
192/16 = 16x/16
x = 12
Substitute the values:
192 = 2(5x) + 2(3x)
= 2(5*12) + 2(3*12)
= 2(60) + 2(36)
192 = 192
