The area of a triangle is defines as A = (1/2)bh. Therefore, A = (1/2)(30)(70) = 1,050 square feet.

Question:

A worker at a factory has to do maintenance on a machine located in a below ground vault. As he enters the vault he starts to become confused, have an increased heart rate and shortness of breadth.

What key molecule is the worker not getting enough of, what is the process called in which cells make ATP under normal conditions, and what should the worker do?

The worker is experiencing a lack of oxygen. Under normal conditions ATP would be generated through aerobic respiration using the Krebs Cycle and Electron Transport Chain. The worker should leave vault and get back up above ground.

Question:

What is the product of multiplying these two binomials: (2x+5)(5x-5)

Justin S.

A common mnemonic for remember how to multiply binomials is FOIL, which stands for First, Outer, Inner and Last. This means multiple the first terms in each parenthesis, so 2x times 5x = 10x^2. Then the outer terms in each parenthesis, so 2x times -5 = -10x. Then the inner terms, so 5 times 5x = 25x. Then the last terms in each parenthesis, so 5 times -5 = -25. Add them all together: (2x+5)(5x-5) = 10x^2-10x+25x-25 **Combine like terms** =10x^2+15x-25
