Answer: The length of each side is 7 yards.
Step-by-step explanation: To solve the perimeter, you add each of the sides. A square has 4 sides of equal length. Divide 28 yards by 4 yards. Therefore, the answer is 7 yards per side.
We can solve it like:
3x^3+3x^2+x+1= (3x^3+3x^2)+(x+1)=
3x^2(x+1)+(x+1)=
= (x+1)(3x^2+1)
Have a good day
In this item, it can be seen that from an expression of,
(4 + 5i) + (-3 + 7i)
Aiko transformed the equation by factoring out the i's from the expression and wrote it as,
(4 + 5)i + (-3 + 7)i
Now this is wrong because i there is not a variable but a notation that 5 and 7 are imaginary numbers. In fact, she cannot factor out the i's because it is not present in both -3 and 4. The answer therefore to this item is the last sentence, "Aiko incorrectly used the distributive property by combining ..."
<h3>Answer:</h3>
- 28/100 = 7/25
- 100/28 = 25/7
<h3>Explanation:</h3>
The wording "the ratio of A to B" means A/B.
Here, "the ratio of the weight of silicon to the weight of crust" means ...
... (28 tons)/(100 tons)
Canceling common factors (and common units), this is ...
... 28/100 = 7/25
___
Then "the ratio of the weight of crust to the weight of silicon" means ...
... (100 tons)/(28 tons) = 100/28 = 25/7
Answer:
y=75+2x
Step-by-step explanation:
Given data
Loading fee=$75
Charge per mile= $2
Let the distance be x
and the total charge be y
Hence the expression for the total charge is
y=75+2x
