Find the solutions to x2 = 27.
O A. x = +3,5
B. x = +39
O C. x = +9.12
D. X = +9.5
Answers
Answer:
A
Step-by-step explanation:
Given
x² = 27 ( take the square root of both sides )
x = ± [tex]\sqrt{27}[/tex]
= ± [tex]\sqrt{9(3)}[/tex]
= ± [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]
= ± 3[tex]\sqrt{3}[/tex] → A

a
13 = 254 and a
33 = 654
Find a
27
Answers
Answer:
The value of a₂₇ is 294
Step-by-step explanation:
a₁₃ = 254
a₃₃ = 654
Now,
a₁₃ = 254 can be written as
a + 12d = 254 ...(1) and
a₃₃ = 654 can be written as
a + 32d = 654 ...(2)
Now, from equation (2) we get,
a + 32d = 654
a + 12d + 20d = 654
254 + 20d = 654 (.°. a + 12d = 254)
20d = 654 - 254
20d = 400
d = 400 ÷ 20
d = 20
Now, for the value of a put the value of d = 20 in equation (1)
a + 12d = 254
a + 12(20) = 254
a + 240 = 254
a = 254 - 240
a = 14
Now, For a₂₇
a₂₇ = a + 26d
a₂₇ = 14 + 9(20)
a₂₇ = 14 + 180
a₂₇ = 294
Thus, The value of a₂₇ is 294
