25^{2x+1}=144 => x = 0.272, by properties of logarithm.

<h3>What is Logarithm?</h3>
  • The opposite of exponentiation is the logarithm.
  • This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.
  • A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.

Given: 25^{2x+1}=144

Taking logarithm on both sides:

log (25^{2x+1}) = log (144)

=> (2x + 1) log (25) = log (144) (As log_b(a)^m = m (log_b(a)))

=> 2x + 1 = \frac{log144}{log25}

=> 2x + 1 = \frac{2.158}{1.397}

=> 2x + 1 = 1.544

=> 2x = 0.544

=> x = 0.272

Hence, 25^{2x+1}=144 => x = 0.272, by properties of logarithm.

If 50% of a number is 150 and 30% of the same number is 90, find 80% of that number.
Alexandra [31]

Answer:

240

Step-by-step explanation:

We know that 50% of the number is 150 so we can assume the number is 300(if its 50% just double that number). Next we use the equation 0.80 x 300 which gives us the answer 240.

Hope I helped

Explanation:
First you have to write the model in an equation form.

6x+5=15

Subtract 5 from both sides

6x=10

Divide 6 from both sides

X=10/6

Please Answer its timed The dimensions of a rectangle are represented by the functions shown. g(x)+3x-4 f(x)=2x-9 Which function
Alenkasestr [34]

Answer:

\boxed{6x^2-35x+36}

Step-by-step explanation:

The dimensions of the rectangle are represented by functions:

g(x)=3x-4 \\f(x)=2x-9

The area is length × width of a rectangle.

length \times width

(3x-4)(2x-9)

Expand brackets and solve.

6x^2-27x-8x+36

6x^2-35x+36
