Answer:

Step-by-step explanation:

so S and Y are complementary...that means when added, they equal 90 degrees.

S + Y = 90

S = 4Y - 185

4Y - 185 + Y = 90

5Y - 185 = 90

5Y = 90 + 185

5Y = 275

Y = 275 / 5

Y = 55 <===== angle Y is 55

S + Y = 90

S + 55 = 90

S = 90 - 55

S = 35

see below

Step-by-step explanation:

4 ^(3x-1)=3

Take the natural log of each side

ln(4 ^(3x-1))= ln (3)

We know that ln ( a^b) = b ln a

(3x-1) ln 4 = ln 3

Divide each side by ln 4

3x-1 = ln(3)/ (ln4)

Add 1 to each side

3x = ln(3)/ ln (4) +1

Divide by 3

x =1/3 [( ln 3)/ ln (4)] + 1/3

x = .792461

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than a certain number of inches

Georgia [21]

So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2
