Simplify the expression by combining like terms: x + 7x

Mathematics

Aneli [31]3 years ago

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

What is m CDJ? <br>please help me I'm super confused.​
Citrus2011 [14]

Answer:

34 degrees.

Step-by-step explanation:

Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.

Drop the parentheses and get 7x - 8 = 90.

Add 8 to both sides 7x = 98.

Divide both sides by 7, x = 14.

Plug that x value into (3x-8), [3(14)-8] = 34 degrees.
