What is the solution to log2 (9x)- log2^3=3?
Svet_ta [14]

Answer:

x = \frac{8}{3}

Step-by-step explanation:

Using the rule of logarithms

log x - log y = log (\frac{x}{y} )

log_{b} x = n ⇒ x = b^{n}

Given

log_{2} (9x) - log_{2} 3 = 3

log_{2} (\frac{9x}{3} ) = 3

log_{2} 3x = 3

3x = 2³ = 8 ( divide both sides by 3 )

x = \frac{8}{3}

The length of a rectangle is 5.9 cm more than 3 times the width. If the perimeter of the rectangle is 57.4cm, what are it's dime
navik [9.2K]

Answer:

l = 23 cm and w = 5.7 cm

Step-by-step explanation:

Perimeter = twice the length plus twice the width

let w = width

let l = length

l = 5.9 + 3w

57.4 = 2(5.9 + 3w) + 2w

57.4 = 11.8 + 6w + 2w

57.4 = 11.8 + 8w

45.6 = 8w

w = 5.7

Substitute 5.7 for 'w' to get 'l':

l = 5.9 + 3(5.7)

l = 23

I need help! can anybody help?​
Alexandra [31]

Answer:

i, m, and then k (use my method to do the other one)

Step-by-step explanation:

The longer than angle the longer the side tht is opposite to it... so for example, each angle and its opposite correspond to each other.. so K it is side K and so on...

first u should find the missing angles, for A, we know the angles 118 and 28 and a triangle is a total of 180 degrees, so add 118 and 28, which will give u 146, now subtract tht from 180 and u get 34, so the missing angle M is 34, now we can see which angles correspond to which side:

K = k

M = m

L = l

so the shortest will be l, then it will be m, and then it will be k
