8x^2-14xy+3y^2 is the answer
Answer:
-2i+8
Step-by-step explanation:
(1+i)(3-5i)
3+3i-5i-5i^2
3-2i-5(-1), because i^2=-1,
3-2i+5
-2i+3+5
-2i+8
Answer:
The fare ride was 11 miles.
Step-by-step explanation:
So it says that for the first mile the taxi charged $4.00 okay? so then it says for each additional mile he charges $1.25 so what i did was add the $4.00 and then kept on adding $1.25. so $4.00 plus $1.25 equals $5.25 so continue adding $1.25 till you get to exactly $16.50.. Count up exactly how many "$1.25's" it took to get to $16.50 so it would be exactly 10 times you had to add $1.25 to it and we cant forget the first mile which was $4.00 so thats an additional mile so then it would 11 miles !
The base area of the prism is calculated as -
Area of prism = Length X Width
We are given that, length = 6 cm and width = 8 cm
<u>Thus, area of prism = 6 cm X 8 cm = 48 cm²</u>
Now, the volume of prism will be calculated as -
Volume of prism = Length X Width X Height
We are given height as = 7 cm
So, volume of prism will be = 6 cm X 8 cm X 7 cm
<u>Volume of prism will be = 336 cm³</u>
The errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
<h3>Writing an expression as an equation</h3>
From the question, we are to determine the errors that Emma made
The given statement is
"The quotient of six and a number, x, is the same as negative two times the difference of x and 4.5"
"The quotient of six and a number, x", can be expressed as
6/x
"Two times the difference of x and 4.5", can be expressed as
2(x - 4.5)
Hence, the errors Emma made are
- She should have used division to represent the quotient of six and x
- She should have used parentheses to show that - 2 is multiplied by (x - 4.5)
