Answer:

1+cos^2(2A)=(1−cos2(2A))+2cos^2(2A)

=sin^2(2A)+2(cos^2A−sin^2A)^2

=(2sinAcosA)^2+2(cos^4A−2cos^2Asin^2A+sin^4A)

=2(cos^4A+sin^4A)

Simplify the expression by arranging the steps in sequence based on the order of operations 1/6(30x+24)-1/7(63-7×)

Answer:

6x-5

Step-by-step explanation:

We apply distributive property to get rid of the first parenthesis, by multiplying each term inside by the factor 1/6:

$\frac{1}{6} (30x+24)-\frac{1}{7} (63-7x)\\\frac{30}{6} x+\frac{24}{6} -\frac{1}{7} (63-7x)\\5x+4-\frac{1}{7} (63-7x)$

now we get rid of the second parenthesis by multiplying the factor " $-\frac{1}{7}$ " times each of the terms inside the parenthesis (notice here that this factor is negative , so it will flip the signs of the terms it multiplies):

$5x+4-\frac{1}{7} (63-7x)\\5x+4-\frac{63}{7} +\frac{7}{7} x\\5x+4-9+x$

Next we combine like terms:

$5x+4-9+x\\5x+x+4-9\\6x-5$
