2.(-8) + (+5)= ?
3.(+9) - (-3) = ?
4.(+12) - (-1) = ?
5. (-7) - (-5) = ?
(-14) - (+2) = ?
1.1 Pull out like factors :
2p + 8 = 2 • (p + 4)
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
2.2 Solve : p+4 = 0
Subtract 4 from both sides of the equation :
p = -4

the measure of DEF?
The expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.
When the two tangent are drawn to a circle from an exterior point then according to this theorem-
The length of these two tangents is equal.
In the diagram below, DE and EF are tangent to o. In the diagram half of the difference of the arc GF and DF is equal to the angle of the measure of DEF. Thus,
Thus, the expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.

Answer:
A
Step-by-step explanation:
∠DEF is a tangent- tangent angle and is measured as
∠DEF = ( arc GF - arc DF), that is
∠DEF = (236 - 124)° → A
