Answer:

To find the left triangle we make the two right triangles equal 1 square, making the area of that 2x2 or 4

Then we take the uppermost triangle on the left and find the area of that which is 2x2 / 2 or 2. Then we find the right uppermost triangle which is 5x 2 /2 or 5. Then we take the rightmost triangle and find that 4x 4 /2 or 8. Then we add the square in the middle which is 3 x 4 or 12.

Add those area 4 + 2 + 5 + 8 + 12. You should get 31.

Hope that helps somewhat. You need to divide the shape into easily usable shapes like squares and triangles.

Answer:

The correct choice is option A. 7^15 / 3^30

Step-by-step explanation:

(3^-6 / 7^-3) ^ 5

(3^-6)^5 = 1 / 3^30

(7^-3)^5 = 1 / 7^15

= (1 / 3^30) / (1 / 7^15)

= 7^15 / 3^30

Vesnalui [34]

Answer:

B. 745 miles

Step-by-step explanation:

Given that

Kim took 3000 miles trip in 4 days

And,

1st day - 850 miles

2nd day - 745 miles

3rd day - 660 miles

We need to find out that how much she travel in the 4th day

So, it is

Situation:
You are signing up for a book club. The get-in price is 6. Every month, you have to pay 2 dollars.

How This Works:
y=mx+b
M=Slope
B=y intercept.

Y intercept is the starting point. The beginning out. In this case, the y intercept is 6. So, in our situation, 6 is the joining fee. The beginning amount. Slope is the the rate of change. The slope in this problem is 2. Since the monthly fee is 2, that would make it the slope
