Answer:
the top one is $12.
Step-by-step explanation:
simple: 48÷4=12 because 4×10=40.
4×2=8. 40+8=48 which is the amount of money it costs, so add the 2 factors that aren't 4 to get your answer. (division is similar to reverse multiplication)
Answer:
When x=4
P(x) =4 - 4(4)^2 + 4(4) -5
=4 - 4(16) + 16 -5
=4 - 64 +11
= -60 + 11
= -49
It’s the first answer, both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
1/2 of x +4
=1/2(2)=1.
1+4= 5
2+6=8
1/2(2)=1.
8-1=7
7-2=5
Circumference=diameter times pi
diameter=12
circumference=12 times pi
we use pi=3.14
circumfernce=12 times 3.14
circumference=37.68 ft
round to tenth
8 is greater than 5 so roundup
37.7ft
