The problems with extra information, are difficult to solve because sometimes, not all data should be used.
Therefore, students begin to doubt the fact that they are not using all the information raised in the problem.
Example:
Problem:
Suppose we have a triangle with a right angle. The problem gives us as data an angle and the sides of the triangle. We want to determine the length of the hypotenuse.
Solution:
Using the Pythagorean theorem we can solve the problem.
The given angle data is an extra information that you should not use for this case.
Replace x and y in the equation with the given point and solve:
-4(-3) - 10(2) = 12 -20 = -8
-8 is not less than -9
(-3,2) is not a solution.
Answer:
identity property of multiplication
Step-by-step explanation:
Identity property of multiplication means the identity stays the same. in other words to multiply by 1.
Answer:
In other words, the base must be at least 9 feet long.
Step-by-step explanation:
The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.
Recall that the area of a triangle is given by:
Since we want to area to be at least 36 square feet:
We are given that the height is eight feet. Substitute:
Simplify:
Divide both sides by four. Hence, our inequality is:
In words, this means that the base must be at least 9 feet long.
you solve the square root of 54a*7b*3
