(1-sin(x))(1+sin(x))=1/1+tan(x^2)

I think  the right side is  tan^2 x    ( the square of tan x)

Left side =  1 - sin^2 x

Right side = 1  / ( 1 + (sin^2 x / cos^2x))

= 1  /    (cos^2x + sin^2x) / cos^2 x

Now sin^2 x + cos^2 x = 1  so

this =  1  /   1 / cos^2x

= cos^2x  = 1 - sin^2 x  = Left side    - Proved

Solve for j.<br> j/-2+7=-12<br> j=
tangare [24]
J/-2 + 7 = -12 multiply both sides with 2

-j + 14 = -24 move -14 to the other side and change sign

-j= -24 - 14
-j = -38 and if you divide -38 with -1 you get + 38
j=38

3x+4(x-8)-14 evaluate for x=11
djverab [1.8K]

Answer:

For X = 11, the expression is equal to 31

Step-by-step explanation:

Hello

For X = 11 you only have to replaced the value into the expression, so:

3(11) + 4(11-8) - 14

33 + 4(3) - 14

33 + 12 - 14

31

Best regards

60 is x% of 12. Find the value of x.
Liula [17]

Answer:

20

Step-by-step explanation:

We can set up a percentage proportion to find the value of x.

\frac{12}{x} = \frac{60}{100}

Now we cross multiply:

100\cdot12=1200\\\\1200\div60=20

Hope this helped!
