The perimeter of the entire rectangle is 12 cm.
1= x^4-16
Given
(x^2-4)(x^2+4)
2. Answer B
-4(3m-3)+(-10+8m)
12m+12-1+8m
12m+8m = 20m
+12 -1= +11
answer: 20m+11
*note negative times a negative equals positive and negative times positive is negative
first: you multiply -4 by 3m which is -12m.
second: you multiply -4 by -3 which is +12
third: find the invisible which is 1. (located right here: +(1) (-10+8m)
fourth: multiply invisible 1 by -10 which is -10
fifth: multiply invisible one by +8m which is +8m
sixth: combine like terms
seventh: answer
The angle must be between the sides.
Two sides and an angle will definitely produce a congruent triangle if the angle is between the two sides; the SAS congruence theorem tells us this.
