Answer:
√28 = 2√7 or roughly 5.29
Step-by-step explanation:
work backwards! sqr of 28 = x^2 that equals 28
√28 = 2√7 or roughly 5.29
Answer:
-2,-6,-18
Step-by-step explanation:
let g1,g2,g3 be three G.M.s between -2/3 and -54
now -2/3,g1,g2,g3,-54 are geometric
n=5
an=a1 r^{n-1}
-54=-2/3 r^{5-1}
r^{4}=-54×-3/2=81=3^4
r=3
g1=a1×r=-2/3×3=-2
g2=a1×r²=-2/3×3²=-6
g3=a1×r³=-2/3×3³=-18
y = 2x + 4
Step-by-step explanation:
Part 1: 14 because 52+ 74 equals 126 divided by 9 equals 14
part 2:7 because 52+ 74 equals 126 divided by 18 equals 7.
