Answer:
HELLO! im confused do u want us to answer all of them:D?
Step-by-step explanation:
????
To start, we need to distribute
multiply 2x by <em>everything</em> in the parenthesis
2x (5 + 3x) - x
2x × 5 = 10x
2x × 3x = 6x²
now we have...
10x + 6x² - x
<em>simplify </em>
<u>6x² + 9x </u>
the coefficient of x is 9!
Answer: All Real Numbers Are Solutions
Answer:
( x-3) ^2 + ( y-1) ^2 = 4
Step-by-step explanation:
The equation for a circle is given by
( x-h)^2 + ( y-k) ^2 = r^2 where (h,k) is the center and r is the radius
( x-3) ^2 + ( y-1) ^2 = 2^2
( x-3) ^2 + ( y-1) ^2 = 4
Answer:
128.8cm^2
Step-by-step explanation:
area of circle with radius 6cm = π6^2
area of circle with radius 9cm = π9^2
shaded region is equal to π9^2 - π6^2
which is 41π
therefore the shaded region is = 128.8cm^2
