Step-by-step explanation:
J=(x+4)²
K=(8-x)
X=5
=J+3k
=(x+4)(x+4)+3(8-x)
=(x²+8x+16+24-3x)
=25+25+40
=90
Alternatively:
J=(5+4)²
J=81
K=8-5
K=3
J+3k
81+3(3)
81+9
90
Answer:
8x
Step-by-step explanation:
Because you are adding the (x+3) there you can immediately you the association property to simplify
(2x + 5x + x) + (3 - 3)
8x + 0 =
8x
The factors are 3 6 and 9
6h+1-h+3
=5h+4
because 6h-1h is 5h and 1+3 is 4
They are opposites of each other.
-13.2 + 8.1 = -5.1
13.2 - 8.1 = 5.1
