5 0

Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

7×3 -4(225÷32)×2

7×3 -4(7.03)×2

21 - 8 (7.03)

21 - 56.25

= - 35.25

Im working with FOIL distribution system, and the distribution says that x times 2x= 2x^2. Why does it make it squared equation?
jek_recluse [69]

Answer:

No, let me explain

Step-by-step explanation:

The definition of squared is a value multiplied by itself, and in this case, 2x(x) x is being multiplied by itself.  Keep in mind that x is a value, so it could be any number.  We can't say that x times 2x equals 2x, because you are multiplying 2x by the value of x.

Yuliya22 [10]

Answer:

22 centimeters

Step-by-step explanation:

<em>1. See how many centimeters are in a meter:</em>

There is 100 centimeters in one meter

<em>2. Multiply each number by 100 to convert the meters to centimeters </em>

0.98 x 100= 98

0.76 x 100 = 76

<em>3. Subtract to find the difference </em>

98 - 76 = 22

<u>Hence, the blue string is 22 centimeters longer than the yellow string.</u>

<u><em>have  great night! :D</em></u>
