Answer:

11/12

Step-by-step explanation:

when answering the question 1/4-(-2/3) you have to think about the denominator which should be equivalent in each fraction.

step one:1/4-(-2/3),4*3=12 so the denominator would have to be 12 with both fractions.

step two:1/4=3/12,2/3=8/12

step three:add 3/12 and 8/12

Verify this trig function. <br> tanysiny = secy-cosy ?

avanturin [10]

$LHS\\ \\ =\tan { y } \sin { y } \\ \\ =\frac { \sin { y } }{ \cos { y } } \cdot \sin { y }$

$\\ \\ =\frac { \sin ^{ 2 }{ y } }{ \cos { y } } \\ \\ =\frac { 1-\cos ^{ 2 }{ y } }{ \cos { y } }$

$\\ \\ =\frac { 1 }{ \cos { y } } -\frac { \cos ^{ 2 }{ y } }{ \cos { y } } \\ \\ =\sec { y } -\cos { y } \\ \\ =RHS$

A rectangle has twice the area of a square. The rectangle has the dimensions of 20 inches by 8

Simora [160]

Answer:

In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.
