Answer:
Ex 1: f(2)-f(1)+f(1÷2)=9÷4
Step-by-step explanation:
f(2)=2²-2×2+2=4-4+2=2
f(1)=1²-2×1+2=1-2+2=1
f(1÷2)=(1÷2)²-2×(1÷2)+2=5÷4
Answer:
x = 25
Step-by-step explanation:
2x-20=30
First, isolate the term with x in it by moving everything else to the other side:
2x = 30 + 20
Simplify like terms:
2x = 50
Further isolate the x by dividing by 2 on both sides:
2x/2 = 50/2
The 2 cancels out on the left, leaving:
x = 25
/ also means division so the answer is 42.75
Answer:
-2a +11b
Step-by-step explanation:
3(a+2b) - 5(a-b)
we apply distributive property:
3*a + 3*2b - 5*a + 5*b
3a+ 6b -5a +5b
-2a +11b
