Squaring" means to multiply a number by itself. Squaring a positive number gets a positive result: (+5) × (+5) = +25. Squaring a negative number also gets a positive result: (−5) × (−5) = +25.

Answer:

This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.

Find the slope intercept

ad-work [718]

<h2>answer: </h2>

c= -7.4

<h2>explanation:</h2>

x = my + c

where x represented x-axis.

y represented y-axis.

m ------- slope

c ------- intercepted point.

then -5= ⅖(6) + c. by multiply by 5

-25 = 12 + 5c

5c = -37

Find the LCM of 8 and 16.

makkiz [27]

LCM stands for least common multiple, and so the LCM of two number is the smallest possible common multiple of the two numbers.

Since 16 is already a multiple of 8 (and since every number is a multiple of itself), the LCM between 8 and 16 is sixteen itself: it is a multiple of 8, it is a multiple of 16, and there couldn't be a smaller one.

Even though this case was trivial, let's do the computation to learn how to do this in general: first of all, you need the prime factorizations of the two numbers:

$8 = 2^3,\quad 16 = 2^4$

The LCM of the two numbers is composed by all the primes appearing in any of the two factorizations. In case a prime appears in both factorizations, we choose the one with higher exponents.

In this case, 2 is the only prime to appear in both factorizations. So, we choose the one with higher exponent, which is 4, and the answer is $2^4=16$ , as we already observed.
