465 -(-45) = x
This creates a double negative which becomes a positive and you solution would be 465+45 =X, X = 510
2.3 is smaller than 2.6: we can see it just by looking at the digits from left to right.
now, where does 2
stand?
its fraction part is equal to
do that means that 2
=2.8
which is bigger than 2.6
so the final order is
2.3 2.6 2
Answer:
A =112 in^2
Step-by-step explanation:
The area of a parallelogram is found by
A = bh where b is the base length and h is the height
A = 14*8
A =112 in^2
Answer:
scalene triangle
Step-by-step explanation:
A scalene triangle has three different angles and none of its sides are equal in length.
Answers:
x = 8
y = 15*sqrt(2)
===========================================================
Explanation:
This is a 45-45-90 triangle. The right triangle is isosceles.
This means the two legs 3x-9 and x+7 are the same length
3x-9 = x+7
3x-x = 7+9
2x = 16
x = 16/2
x = 8
If x = 8, then each leg is...
3x-9 = 3(8)-9 = 24-9 = 15
x+7 = 8+7 = 15
Each leg is 15 units long to help confirm we have the correct x value.
---------------
The hypotenuse y is exactly sqrt(2) times that of the leg length.
Therefore, y = 15*sqrt(2) since earlier we found each leg is 15 units long.
15*sqrt(2) = 21.213 approximately
