2a2b-6ab2+9ab+5 is right answer
Answer:
Step-by-step explanation:
<u>The diameter is the hypotenuse of the triangle:</u>
- d = √8²+6² = √100 = 10 cm
<u>Area of the semicircle:</u>
- A = 1/2πr² = 1/2(3.14)(10/2)² = 39.25 cm²
<u>Area of the triangle:</u>
- A = 1/2bh = 1/2(6)(8) = 24 cm²
<u>Shaded area:</u>
Answer:
Step-by-step explanation:
I’m in middle school
For this problem I would change:
2x + 3y = 25 into
-2x - 3y = -25
Then, I would add up both equations by lining them up top of another.
5x + 3y = 31
+ -2x - 3y = -25
3x = 6
x = 2
Now that you have x, solve for y.
5x + 3y = 31
5(2) + 3y = 31
10 + 3y = 31
3y = 21
y = 7
So, x is 2 and y is 7.
Check to see if the values are correct by plugging them into the other equation.
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25
Since the values are correct, the solution to this problem is A (2, 7).
Step-by-step explanation:
Area of triangular prism =1/2 ×base×height
550=1/2×22×h
h=550/11
h=50m
hope it helps.
