Answer:
(1) C
(2) C
(3) 4
(4) False
Step-by-step explanation:
(1) If DF = FB, then point F is called the midpoint and segments DF and FB are congruent.
(2) If ray FA bisects angle EFB, then angles EFA and AFB are congruent. If measure of angle EFA = 47 degrees, the measure of angle EFB = 47 degrees.
(3) If DF = x+2, FB = 2x+1 and DB = 15, then
DF + FB = DB
x+2+2x+1=15
3x+3=15
3x=15-3
3x=12
x=4
(4) If x=4, then
DF=4+2=6
FB=2·4+1=9
Since DF is not congruent to FB, F is not a midpoint. False
6x+18y+12z
Hope this helps!
Answer:
Substitute
Step-by-step explanation:
Substitute the values given in the function
and you will get the answer.
P.s. It depends on the question
Find the cubic root of the first term ( numbers)
∛49 = 3.659
∛81 = 4.326
∛121 = 4.946
∛ 343 = 7
Because ∛343 is the only whole number answer ( no decimal places) the last answer is the correct one.
