Answer:
Janice examines the given triangle and estimates that the longest side has a length of 25 units―if it is a right triangle. How does her estimate compare to the actual length? It is under by approximately 0.6 units.
Step-by-step explanation:
In order to solve the given expression follow these steps:
1. Take the square roots on both sides in order to get rid of the power on the left side:
√(x-5)² = ±√3
x - 5 = ±√3
2. add 5 on both sides:
x-5 + 5 = 5 ±√3
x = 5 ±√3
Then, the solution is x = 5 ±√3
Answer:
2<em>x= 1
/2
y+ 2</em>
Step-by-step explanation:
Solve for x.
<em>2x−y=4</em>
Add y to both sides.
<em>2x−y+y=4+y
</em>
<em>2x=y+4</em>
Divide both sides by 2.
<em>2x
/2 = y+4
/2</em>
<em>x=
1/
2
y+2</em>
