Answer:
x=19
Step-by-step explanation:
The 2 angles are inside of a right angle. We know this because of the little square in the corner. Therefore, they are complementary angles. When they are added together, they must equal 90 degrees.
3x+11+22=90
Combine like terms by adding 11 and 22
3x+33=90
We want to find out what n is. In order to do this, we have to get n by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
33 is being added to 3x. The opposite of addition is subtraction. Subtract 33 from both sides.
3x+33-33=90-33
3x=90-33
3x=57
x is being multiplied by 3. The opposite of multiplication is division. Divide both sides by 3.
3x/3=57/3
x=57/3
<u>x=19</u>
Answer:
The numbers are 4 and 6
Step-by-step explanation:
Let:
- x - the smaller even consecutive integer
- x+2 - the larger even consecutive integer
we know that
solve for x
We can use the quadratic formula for quadratics in the form
to give us an answer of 4 and -3
Since the question states positive and even we use 4 and that gives us 6 as the other answer
4 and 6
