Greeley [361]

Using sin(A+B) = sinAcosB + cosAsinB

sin20cos40 + cos20sin40 = sin(20+40) = sin60degree

= $\frac{ \sqrt{3}}{ 2}$

cheryl used 40% of her money to buy a dress and 1/5 of the remainder to buy a pair of shoes. She then donated $60 to charity and

Ede4ka [16]

Let x be total amount of money

dress: 40% of x = 0.4x

left: x - 0.4x = 0.6x

shoes: 1/5x 0.6x = 0.12x

left: 0.6x - 0.12x = 0.48x

donate: $60

$132 left over

0.48x - 60 = 132

solve for x:

0.48 - 60 = 132

0.48x = 192

x = $400

What goes in the blanks? (a2 +___+1)−(___+5a+___)=4a2 −2a+7

andrey2020 [161]

Answer:

4a2 + 4a + 1 = (2a +1)^2 = (2a + 1)(2a + 1)

4 − 4a + a2 = (2 - a)^2 = (2 − a)(2 − a)

4a2 − 4a + 1 = (2a -1)^2 = (2a − 1)(2a − 1)

4 + 4a + a2 = (2 + a)^2 = (2 + a)(2 + a)
