Big rectangle
3x-4 (2x+2) = 6x^2-8x+6x-8
=6x^2-2x-8 = 3x^2-x-4
Small rectangle
(X-3) (x-6) = x^2-3x-6x+18
=x^2-9x+18
Big-small= 2x^2+8x-22 is the area of the shaded region
360 / 12 = 30
So, it's 30 degrees.
Incidentally, a 12 sided polygon is called a dodecagon.
Answer:
The slope is -6 and the y intercept is 0
Answer:
A. 7 years old
Step-by-step explanation:
6x-7=35 is the equation.
Add 7 to both sides, which gives you 6x=42.
Then both sides by 6, so 6/6=x and 42/6=7
So, x=7.
Since x is his daughter's age, x=7, so his daughter is 7.
46.50 - 19 = 5.50x
We get the 46.50 from her budget and the 19 from the shirt she wants to buy. If we subtract 19 from 46.50, we'll get the amount of money Jasmine can spend on bracelets.
46.50 - 19 = 27.50
She has $27.50 to spend on bracelets. Now, we divide that by 5.50 (the price of a bracelet) to see how many she can buy.
27.50 ÷ 5.50 = 5
Jasmine can buy 5 bracelets.
Hope this helps!
