Answer:
49x+36
Step-by-step explanation:
Hey There!
for this question they would like you to simplify the expression using distributive property
To do this the first step is to distribute the 9 in to everything that is in the parenthesis
9x5x=45x
9x4=36
so now we have
45x+36+4x
the next step is to combine like terms
the only like terms in the expression are 45x and 4x so we just add the two together
45x+4x=49x
so now we have 49x+36
In conclusions the simplified version of that expression is 49x+36
Oki so the missing angle is also 2x + 15 since that’s equal so add all three of those together and equal it to 180 and solve
Answer:
6 – x ft
Step-by-step explanation:
If a 6-foot board is cut in two pieces, both lengths could be anything that add up to 6 feet since the problem did not specify where the board was cut.
So if one piece is x feet long, the other must be 6 - x feet long because:
x + (6 – x) = 6
Answer:
See explanation.
Step-by-step explanation:
Part C)

When adding a positive to a negative, the result will be the sign of the larger absolute value. In this case, 10 is greater than 5, so the result will be negative.
Adding a negative is also the same thing as subtracting a positive.

For your second problem, 5 is larger than 3, so the result will be positive.

-----
When adding a positive to another positive, the result will be positive.

When adding a number to zero, the answer will always be the number.

Part D)
When multiplying a positive times a negative, the result will always be negative.


-----
When multiplying a positive times a positive, the result will always be positive.

When multiplying a positive or a negative times zero, the result will always be zero.
