Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is

Step-by-step explanation:
Evaluate:

When a=-4, b=2, c=-3, and d =4
Solution:
Substitute, a=-4, b=2, c=-3, and d =4 in above expression we get


Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is

Answer:
10201
Step-by-step explanation:
=(101)²
=(100+1)²
={100²+2(100)(1)+1²} [(a+b)²=a²+2ab+b²]
=10000+200+1
=10201

Answer:
1.25 = X
Step-by-step explanation:
5-2x+2=12-4x-2x
Combine all like terms here.
7-2x=12-6x

7=12-4x
Subtract 12 on both sides.
-5=-4x
Divide by -4.
1.25=X
