Step-by-step explanation:
(x + 3)² − 5 because :
(x + 3)² − 5 = x² +6x+9 -5 =x²+6x+4
‘| |’ means modulus.
It’s turns the internal value positive.
We get a negative answer while finding the area of a triangle because there points in the quadrant other than the 1st quandrant i.e where all values are positive
Area of a triangle can never be negative, so we use modulus
Answer: 7, 2 in order.
Step-by-step explanation:
We can combine like terms.
5 - 4 + 1 = 2.
Therefore, 5 - 4 + 7x +1 = 7x + 2.
Thus, the blanks are 7, 2 in order.
C, 25. You take half of the variable B, so 5 in this case, because B=10. Then you square it. 5^2 is 25.
