The answer is -220
What you do is take -7 and multiply that by (1+2+3+4+5+6+7+8+9+10+11) and then after that add 11 again and multiply it by 22. It would look like this.
-7 x (1+2+3+4+5+6+7+8+9+10+11) +11 x 22
Simplify that to -7 x 66 +11 x 22
now multiply -7 and 66 to get -462
-462 +11 x 22
multiply 11 and 22
-462 + 242
and your final answer will be -220
Step-by-step explanation:
First, find the slope between the points.
m = (y₂ − y₁) / (x₂ − x₁)
m = (24 − 17) / (20 − 15)
m = 7/5
Next, write the equation in point-slope form, using either of the points.
y − 17 = 7/5 (x − 15)
If desired, simplify.
y − 17 = 7/5 x − 21
y = 7/5 x − 4
because the sides are the same and angle L = 58, that means that angle J is also 58, so LKJ would be 180-58-58 = 64 degrees
if JKM = 48, M = 90
so J = 180 -90 -48 = 42 degrees
Answer:
Area= 50.24 squared cm.
Circumference= 25.12 cm.
Step-by-step explanation:
To find the area of a circle- A= 3.14*(4 cm squared). ( The 4 cm is your radius. Half of the diameter.) After you square your radius you get 16cm squared. You then go onto multiply the 16 cm squared by 3.14 to get 50.24 cm squared.
To find the circumference of a circle- C= 2*(3.14)*(4cm). (Again the 4cm is your radius. Half of the diameter.) After you multiply the 2 and 3.14 you get 6.28. You then multiply the 6.28 by 4 cm to get 25.12 cm.
