Take the lengths as 2x and 3x.
As per the question,
2x + 3x = 45
5x = 45
So, x = 45/5 = 9
To find the length of 1st segment : 2x = 2 * 9 = 18
And the length of the 2nd segment: 3x = 3 * 9 = 27

Hope this helps! :)

2. Solve for x. More than one answer may be correct. Select all correct choices.*

shtirl [24]

Answer:

None of these are correct

The value x = 35 is correct

Explanation:

Step(i):-

Given

$log^{2} _{10} + log^{(x+5)} _{10} = 2$

We will apply logarithmic formula

log(a) + log (b) = log a b

logₓ a = b

⇒ a = xᵇ

Step(ii):-

$log^{2} _{10} + log^{(x+5)} _{10} = 2$

$log^{2(x+15)} _{10} = 2$

⇒ 2 ( x + 15 ) = 10²

⇒ 2 x + 30 = 100

⇒ 2 x = 70

⇒ x = 35

Final answer:-

x = 35

Verification:-

$log^{2} _{10} + log^{(x+5)} _{10} = 2$

$log^{2(35+15)} _{10} = 2$

$log^{(100)} _{10} = 2$

$log^{(10)^{2} } _{10} = 2$

log x ⁿ = n log x

2 log¹⁰ ₁₀ = 2

2 = 2 ( log¹⁰ ₁₀ = 1
