Greetings from Brasil...
Let's apply the given formula:
A = (1/2)·B·H
The base of this polygon (in this case, the triangle) is B
B = X² - 2X + 6
The height of this polygon is H and is H
H = X + 4
Applying these values (B and H) in the given formula.....
A = (1/2)·B·H
A = (1/2)·(X² - 2X + 6)·(X + 4)
A = (1/2)·(X³ + 2X² - 2X + 24)
A = (X³/2) + X² - X + 12
OR
A = (X³ + 2X² - 2X + 24)/2
Answer:
i dont know
Step-by-step explanation:
.
Answer:
A:
You do 65 divided by 25 = 2.6
52 divided by 2.6 = 20
Ryan has 20, so the answer is Ryan.
Hope this helps!
Answer:
The length of the hypotenuse is 17.
Step-by-step explanation:
I found this out by doing:
15 x 15 = 225
8 x 8 = 64
225 + 64 = 289

Hope this helps you! :)
3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
