Answer:
Step-by-step explanation:
C.
x² + 10x + 25 = (x+5)²
Answer:
Below in bold.
Step-by-step explanation:
2x + 18 + 3x + 12 = 180 (property of a cyclic quadrilateral).
5x = 180 - 18 -12
5x = 150
x = 30
So m < A = 2(30)+18
= 78 degrees.
63 / 5 = 12.6 or 12 remainder 3
Answer:
A- By simplifying 25 to 52 to make both powers base five and subtracting the exponents
Step-by-step explanation:
Change 25 into 5².
Apply the Quotient of Powers Property. (Subtract the exponents.)
Answer: A- By simplifying 25 to 52 to make both powers base five and subtracting the exponents
We need to find which statement is not true:
Let us check each statement:
-They are opposite numbers.
Opposite numbers have the same distance away from zero. Hence, 7 and -7 are opposite numbers.
-They form a zero pair:
7-7 =0, the statement is true.
- They have the same absolute value
The absolute value is the not negative value no matter the sign.
Hence, l7l= 7 and l-7l= 7.
-They have a sum of -14.
Then:
7+(-7) = 0
Therefore, the last statement "They have a sum of -14" is not true.
