Answer:
32x ft²
Step-by-step explanation:
The area of the garden plus patio is ...
(x +8)² = x² +16x +64
The area of the patio is ...
(x -8)² = x² -16x +64
The area of the flower garden is the total area less the patio area:
(x² +16x +64) -(x² -16x +64) = 32x . . . area of the flower garden
<span>cos(-120°), sin(-30°), -sin(150°)
This problem requires you to understand the symmetric identities for the sin and cos functions. sin(-150°) is in the 3rd quadrant and is 30° away from the X axis. Now let's look at all the possibilities:
cos(-120°) - Also in the 3rd quadrant and 30° away from the Y axis. MATCH.
sin(150°) - It's in the 2nd quadrant. Will have opposite sign. Not a match.
sin(-30°) - It's in the 4th quadrant. The signs will match. It's also 30° away from the X axis. MATCH.
-sin(150°) - The identity sin(-a) = -sin(a) applies here. MATCH.
cos(60°) - In 1st quadrant. Result will be positive. Not a match.
cos(-60°) - In 4th quadrant. Result will be positive. Not a match.</span>

Answer:
probability of blue ball is 1/2
probability of yellow ball is 1/4
Step-by-step explanation:
We have given 6 blue balls 3 green balls and 3 yellow balls
Total number of balls are: 12
we have to find the probability of choosing a blue ball:
Then the ball was placed in the bag since, it is given replacement
Now, we have to find probability of choosing a yellow ball
Answer: 12+8x
Step-by-step explanation:
1) 4(3+2x)- Distribute the 4
