Answer:
<h3>No, it is not a right triangle</h3>
Step-by-step explanation:
In order to know whether the triangle is a right angle, we need to show that the square of the longest side is equal to the sum of the square of the other two sides
Longest side = 17in
other two sides = 8in and 9in
Check:
17² = 289
Sum of the square of other two sides
= 8² +9²
= 64 + 81
= 145
Since 17² ≠ 8² +9², hence the triangle that Landon created is not a right triangle
To find your answer you must substitute y for 0.8
4x + (8)(0.8) = 40
Now solve for x
====================================================================
SOLVING...
<span>4x + (8)(0.8) = 40
</span><span>4x + 6.4 </span>= <span>40
</span>
Subtract 6.4 from each side
<span><span><span>4x</span>+ 6.4 </span>− 6.4 </span>= <span>40 − <span>6.4
</span></span>4x = 33.6
Divide each side by 4
4x ÷ 4 = 33.6 ÷ 4
x = 8.4
<span>The expression is missing from the question, but here is the given expression which I got from a similar question.
48 + 54 = ___ ´ (8 + 9)
Theleft-hand side of the equation is:
48 + 54 = 102
Now the right-hand side of the equation:
A </span>× (8+9) = Right-hand side
A × (8+9) = 102
Solving for the unknown variable A,
A × 17 = 102
Dividing by 17 on both sides,
A × 17 ÷ 17 = 102 ÷ 17
A × 1 = 6
A = 6
Hence,
48 + 54 = 6 x (8 + 9)
Yes. 3/15 can still be simplified
Divide 3 from numerator and denomoinator.
3/3 = 1
15/3 = 5
1/5 is the simplified form.
hope this helps

where (a,b) are the coordinates of the center and r , the radius.
For the given equation: a = 3 , b = -1 and r = 9
hence centre = (3 ,-1) and radius = 9
