How can I easily see if two cell values are equal to each other?

The easiest option is to use the '=' operator and set both cells equal to each other Example: A1 = B1 Excel will output TRUE or FALSE

Find the area of a triangle with sides 3, 4 and 5

First of all, we can recognize that a 3-4-5 triangle is a right triangle! The side with length 5 is the hypotenuse. Sides with length 3 or 4 can each either be the base or the height. Also remember that the formula for the area of a triangle is (1/2) * (base) * (height). Based on this, the area is: (1/2) * (3) * (4) = (1/2) * (12) = 6 Also notice that it does not matter if 3 or 4 are the base or the height!

What is the value of x when: 16x + 2(-4 - 3x) = 1 + x ?

To solve this problem, we need to remember our order of operations and distribute the 2. When we do that, we get: 16x - 8 - 6x = 1 + x Then we need to simplify the equation further, by adding like terms on each side: 10x - 8 = 1 + x After this, we need to move all the x to one side (combining like terms) and all the numerical values to another side: 10x - x = 8 + 1 9x = 9 After this, we can now solve for x by dividing both sides by 9 x = 1
