The arcs in the corners of the triangle mean that all 3 angles are the same.
Because the 3 angles are all the same this means that all 3 sides are also the same.
To solve for X, we can set 2 of the equations to equal each other and solve for x:
6x-3 = 3x +6
Add 3 to each side:
6x = 3x +9
Subtract 3x from each side:
3x = 9
Divide both sides by 3:
x = 9/3
X = 3
And if you replace x with 3 in each of the equations, they all equal 15.
should be 916191, because 916191 over 1 would be 916191
Answer:
a = 3, -3
Step-by-step explanation:
Multiply (a+3)/(a+3) to 2/(a-3) and multiply (a-3)/(a-3) to 2/(a+3) to get:
2(a+3)/(a-3) and 2(a-3)/(a+3) which equals (2a+6)/(a^2-9) and (2a-6)/(a^2-9)
add those two together to get (4a)/(a^2-9) which is equal to a/(a^2-9) on the other side. Cross multiply to get 4a^3 - 36a = a^3 - 9a, add/subtract like terms and you get a = 3 or -3
Answer:
9.5 m
Step-by-step explanation:
If width is -- x
12.4 + x + 12.4 + x = 43.8
2x = 19
x = (19/2)
x = 9.5 m
Thenks and mark me brainliest :))
