Answer:
x =417.6
Step-by-step explanation:
0.5x+78.2=287
Subtract 78.2 from each side
0.5x+78.2-78.2=287-78.2
.5x =208.8
Divide each side by .5
.5x/.5 = 280.8/.5
x =417.6
Answer:
69.45 m to the nearest hundredth.
Step-by-step explanation:
I guees you want the length of one side.
A square has 4 sides of equal length and the area = s^2 where s = length of each side.
So the length of a side of a square of area 4823
= √(4823)
= 69.4478 m.

The answer is Strong Positive
If a² + b² = c², then the triangle is <u>right</u>.
So we have (8)² + (11)² <u>?</u> (13)²
(8)² is 64, (11)² is 121, and (13)² is 169.
So we have 64 + 121 <u>?</u> 169
64 + 121 is 185 and we can see that 185 > 169.
This triangle would not be a right triangle.
In fact, it would be an acute triangle.
So no, it's not a right triangle.
