100•-4=-400 -400•40=-16000
Answer:
-2 and -7
Step-by-step explanation:
This problem is about using the Factoring X.
Two numbers will multiply to the number placed at the top. These same two numbers will add to the value placed on the bottom.
Let's look at the factors of 14.
1 • 14 = 14
2 • 7 = 14
Now let's look at their sums.
1 + 14 = 15
2 + 7 = 9
We can see that 2 and 7 multiply to 14 and add to 9.
However, we need them to add to -9.
Note that two negative numbers multiplied will become positive.
-2 • - 7 = 14
Now let's look at their sum.
-2 + (-7)
Simplify the negative.
-2 - 7 = -9
We can see that -2 and -7 multiply to 14 and add to -9.
Hope this helps!
Answer:
3 starts for the first one
Step-by-step explanation:
Answer:-
1. False. A square is always a rhombus.
2. True. When all sides are equal in a rectangle then it is square.
3. False. In parallelogram opposite sides are equal .But kite is grouped into two pairs of congruent sides that are adjacent to each other. Thus A parallelogram can never be a kite.
4.True. A rhombus with interior angle 90° is square.
5.True. A trapezoid is a quadrilateral who has two opposite sides which are parallel to each other but kite is grouped into two pairs of congruent sides that are adjacent to each other.It may not have one pair of opposite parallel sides. Only rhombus is a kite which can be trapezoid.
