I wrote the algebraic expressions in order for you. When I show the up arrow, it represents that the number after the arrow is an exponent. Hopefully this helps. :D
4 • (n^3 - 7)
(5 x n) + 3
(n^2) - 15
3 + (5 x y)
Answer:
value of pi
Step-by-step explanation:
area of circle = pi x r x r
d= 2 x r
r = 1
pi x 1 x 1 = pi
Answer:
92
Step-by-step explanation:
let's start off by plugging 2 for every a in the equation and 4 for every b.
4a+2b^2-2(a-3b)=?
4(2)+2(4)^2-2(2-3(4))=?
8+8^2-2(2-12)=?
8+64-2(-10)=?
8+64+20=?
?=92
