I only know B
Answer
X= 1 over 7 hj + 27 over 7
Answer:
Step-by-step explanation:
a=4 b=12
2a+3b=
2*4+3*12=
8+36=
44
a²-b+10=
4²-12+10=
4*4-2=
16-2=
14
(ab)²-(a+b)²=
(4*12)²-(4+12)²=
48²-16²=
(48+16)(48-16)=
64*32=
2048

Infinite solutions. This equality is true for any value of n.
a.
You would find the radius by halving the diameter. Then you use the equation
