The answer is Y = 63

Here's how I got my answer:

Step 1: Add 4 to both sides. Which leaves us with $Y/7 = 5 + 4$

Step 2: Simplify $5 + 4$ to 9. Which leaves us with $Y/7 = 9$

Step 3: Multiply both sides by 7. Which leaves us with, your answer, Y = 63

How to express cos 3x in terms of cosx

Elena-2011 [213]

$\cos3x=\cos(x+2x)=\cos x\cos2x-\sin x\sin2x$
$=\cos x(\cos^2x-\sin^2x)-2\sin^2x\cos x$
$=\cos^3x-\cos x\sin^2x-2\sin^2x\cos x$
$=\cos^3x-3\cos x\sin^2x$
$=\cos^3x-3\cos x(1-\cos^2x)$
$=\cos^3x+3\cos^3x-3\cos x$
$=4\cos^3x-3\cos x$

Naomi used a rectangle, a square, and a right triangle to form the following figure.

jeyben [28]

Answer:

102 cm2

Step-by-step explanation:

First you want to find the area of the entire rectangle by multiplying the 2 sides.

20cm x 6cm = 120

Then you want to find the area of the other two shapes (in this case the square and triangle). Also use the other sides to find the lengths of the triangle.

Square = 3 x 3 = 9

triangle = 6 x 3 = 18 / 2 = 9

So then all you have to do is subtract the squares and triangles area from the total rectangle.

120 - (9 + 9)

120 - 18

102 cm2

Hope this helps! Feel free to message me for anymore help!
