In this question, you have to use the Pythagorean theorem. (the formula is in the box, ‘a squared’ and ‘b squared’ is used to find the legs of the triangle, while the ‘c squared’ in the formula is used to find the hypotenuse of the triangle.
Step-by-step explanation:
16 - 4(3x - 5)
16 - 12x + 20
12x = 16 + 20
12x = 36
x = 36/12
x = 3
I find it convenient to let a graphing calculator help me with factoring. It shows the roots to be -7, 1/5, 2. Hence the factorization will be
.. = (x +7)(5x -1)(x -2)
Answer:
Is B
Step-by-step explanation:
7 7/8 inches
All I did was multiply 2 1/4 by 3 1/2.
I hope this helps!
