If one cant be given, then most likely 12. Using 3 as the integer, as they would be the second lowest number.. and multiplying it by 4, 12.
2*14=28
28+24=52
52*2=104
104+15=119
her paycheck was $119
We can solve for the 3 triangle sides.
The left side is easy 6.
Second side² = 7² + 4²
Second side² = 49 + 16
Second side = square root (65)
Second side =

8.0622577483

</span>
Third Side² = 7² + 2²
Third Side² = 53
Third Side =

7.2801098893
</span>

When we know 3 sides, we use Heron's formula for calculating area:
Perimeter =
<span>
<span>
<span>
21.3423676376
</span>
</span>
</span>
Semi-Perimeter =
<span>
<span>
<span>
10.6711838188
</span>
</span>
</span>
Using Heron's Formula
area = square root (<span>10.6711838188 * </span><span>4.6711838188 * </span>
<span>
<span>
<span>
2.6089260705

)
area = square root (441)
area = 21
Yes, it's just that "easy". LOL
Answer:
X = 44°
Step-by-step explanation:
The angle other than 68°and and x is also 68° because its a isosceles triangle.
so 68° + 68° + x = 180° (angle sum property)
136° + x = 180°
x = 180 - 136
= 44°
hope this helps.
1/3 and 2/5 --> what we need is a least common denominator
(1/3)x5 (2/5)x3
5/15 and 6/15
so he needs to paint his room two more times which will make the 5/15 become 15/15
you start with 5/15 and you need to add "5/15" two more times which will make 15/15
so you do that to 6/15
6/15+6/15+6/15=18/15=1 3/15 or 1 1/5 cans of paint ANSWER
