(2) diagonal are congruent
Answer:
n=2
Step-by-step explanation:
(-y + -2 ) + ( 3y + 6)
-y + 3y = 2y
2 + (-6) = -4
equals to ( 2y - 4)
How many groups were there
Answer:
The answer is B
Step-by-step explanation:
5x² +9x +3 - (6x ² -3x)
this is easier if you distribute the negative in front of the perenthesis so...
5x² +9x +3 + (-6x² + 3x)
then you just combine the terms with the same variable and exponent
-x² +12x +3
Answer:<u> HI</u>
w = 8
Step-by-step explanation:
hi
P = 2L + 2W
P = 72
L = 2W + 4
72 = 3(2W + 4) 2W
72 = 6W + 8 + 2W
72 =8W + 8
64 = 8W
W = 8
if the width is 8, then the length is thrice that plus 4 or 28 + 28 + 8 + 8 = 72
