Answer:
B and F
Step-by-step explanation:
Trinomials are polynomials with 3 terms
A has only one term → monomial
B has 3 terms → trinomial
C has 2 terms → binomial
D has one term → monomial
E has 2 terms → binomial
F has 3 terms → trinomial
Answer:
x=40
Step-by-step explanation:
x=4(x+10)÷5
x=(4x+40)÷5
5x=4x+40
x=40
Answer: 8
Step-by-step explanation: the given expression is 2n-3
so when n=1, we will get, 2(1)-3=2-3=-1
when n=2, we will get, 2(2)-3= 4-3=-1
when n=3, we will get 2(3)-3= 6-3=3
when n=4, we will get 2(4)-3 = 8-3=5
so the required result of expansion is -1+1+3+5=8
answer is 8.
hope that helped!
