Answer:
The expressions are equivalent
Step-by-step explanation:
We can start by simplifying the first expression:
1.25x+4+0.75x-3
Move like terms so that they are together:
1.25x+0.75x+4-3
Now, combine like terms:
2x+1
The expressions are equivalent
From the given information we can assume that (-1; 2) point is the same as x=-1 and y=2.
The easiest way to solve this problem is to put -1 and 2 instead of x and y
in this way you will get answer C
2 - 2 = (3/2)*(1 - 1) which means that 0 = 0 and this answer is correct.
Answer: C
Answer:
144 cm
Step-by-step explanation:
P=4l
P=4*36
P=144 cm
The result of simplifying each number 64²/₃ 64²/₃ using the exponent rules is 256
To solve this exercise we have to resolve algebraic operations following the exponent rules.
64²/₃ * 64²/₃
The base number 64 is the same that: 4³, then we get:
(4)³ ⁽²/₃⁾ * (4)³ ⁽²/₃⁾
Using the power of a power rule that indicates that: the exponent result will be the multiplication of these exponents, we have:
4⁽³*²/³⁾ * 4⁽³*²/³⁾
4⁽⁶/³⁾ * 4⁽⁶/³⁾
(4)² * (4)²
Using the product rule that indicates that: the exponent result will be the addition of these exponents, we have:
4⁽²⁺²⁾
4⁴
4*4*4*4
256
<h3>What is an exponent?</h3>
In mathematics an exponent is the number of time that a number, called (base) is multiplied by itself. It is also called, power or index.
Example: 3² = 3*3 = 9
