Carla = 5 years old
Jim = 2 years old
Peter = 15 years old
(Peter was 14 years old one year ago)
5+2=7
7x2=14 (14 is the age from one year ago meaning 15 is the current age)
15-2=13
Answer:
The answer will always be negative
Step-by-step explanation:
The rule is if you multiply positive by positive it will equal positive.
If you multiply negative and negative it will equal positive.
But if you multiply negative and positive it will equal negative.

<u>Right Triangles</u>
A right triangle can be identified by the fact it has an internal angle of 90°. In a right triangle, the trigonometric ratios stand.
Let's consider the triangle to the left. We need to calculate side c, one of the legs of the triangle. We can use the angle adjacent to it (60°) or the angle opposite to it (30°) with the appropriate trigonometric ratio.
We'll use the adjacent angle, and

Solving for c

Rationalizing

Now for the triangle to the right. The side h is the hypotenuse. Again, any of the two angles can be used (though they are equal, for it's an isosceles triangle). For any of them it is true that

Answer:
81+86+89+96 equals an average of 88. If she wants an average of 90 she needs to score a 93 and 96 on the next two tests.
