Answer:
98
Step-by-step explanation:
So we have the expression:
[tex]6x+10y[/tex]
And we want to evaluate it when x is 3 and y is 8.
So, substitute:
[tex]=6(3)+10(8)[/tex]
Multiply:
[tex]=18+80[/tex]
Add:
[tex]=98[/tex]
And we're done!

Select the correct product. ( x2 + 6 x + 9)(3 x - 1) 3 x3 + 17 x2 + 21 x - 9 3 x3 - 17 x2 - 21 x - 9 3 x3 + 19 x2 + 27 x + 9 3 x3 + 19 x2 + 9 x - 9
Answer:
[tex] \boxed{ \bold{{ \boxed{ \sf{3 {x}^{3} + 17 {x}^{2} + 21x - 9}}}}}[/tex]
Option A is the correct option.
Step-by-step explanation:
[tex] \sf{( {x}^{2} + 6x + 9)(3x - 1)}[/tex]
Use distributive property
⇒[tex]{ \sf{ {x}^{2} (3x - 1) + 6x(3x - 1) + 9(3x - 1)}}[/tex]
⇒[tex] \sf{3 {x}^{3} - {x}^{2} + 18 {x}^{2} - 6x + 27x - 9}[/tex]
Collect like terms
⇒[tex] \sf{3 {x}^{3} + 17 {x}^{2} + 21x - 9}[/tex]
Hope I helped!
Best regards! :D
Answer:
3x^3 + 17x^2 + 21x - 9
Step-by-step explanation:
Use distributive property.
First distribute the 3x
3x times x^2 + 6x + 9. Distribute = 3x^3 + 18x^ 2 + 27x
Now we distribute the -1
-1 times x^2 + 6x + 9. Distribute = -x^2 -6x - 9
We Add both answers-
3x^3 + 18x^2 + 27x
+ -x^2 -6x - 9

Step-by-step explanation:
I added all the choices together I picked the one that had the same answer. Good luck!
Owen's model is represented by -
3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Owen creates this model to determine the product of two decimals.
The equation that represents the Owen's model is -
3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44
Therefore, Owen's model is represented by -
3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many students are boys?
Answer:
15
Step-by-step explanation:
The ratio has been simplified so it may be hard to read.
To fix this multiply both the 5 and 7 by 3
This will give you 15:21
15 + 21 = 36 which is the total number of students.
Keeping the ratio in the same order means that there are 15 boys.
Answer:
There are 15 boys in the class.
Step-by-step explanation:
There are several ways to solve this, but here's how I did it:
5 (boys) : 7 (girls) = 12 students. There are 26 students, so we need to multiply this by 3.
15 (boys) : 21 (girls) = 36 students.

owenn goes on a camping trip with his family cabin rentals are $430 for the week, kayak rentals are $7 per hour and paddle boards are $9 an hour, write an algebric expression to represent how much the family will spend if they stay for one week and plan on renting both kayaks and paddle boards while on their tripoi
Answer:
430 + 16h
Step-by-step explanation:
They are staying for a week ($430)
They are renting both a kayak ($7 per hour) and paddle board ($9 per hour), without defining the amount of hours. Create a variable, for example H for hours.
To create the expression, take the $430, the $7 per hour and $9 per hour, or 430 + 16h.

A leg of a right triangle measures 12 cm. The hypotenuse of the triangle measures 37 cm. What is the measure, in centimeters of the other
leg of the triangle?
25
35
39
49
Answer:
The answer is 35Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where a is the hypotenuse
Substitute the values into the above formula and solve
That's
[tex] {37}^{2} = {b}^{2} + {12}^{2} \\ {b}^{2} = {37}^{2} - {12}^{2} \\ { b}^{2} = 1369 - 144 \\ {b}^{2} = 1225 \\ b = \sqrt{1225} [/tex]We have the final answer as
35Hope this helps you
Answer:
35
Step-by-step explanation:
To solve for the hypotenuse of a right triangle, we use the Pythagorean Theorem, which is an equation to solve for the length of the hypotenuse given the two sides. The equation is a^2+b^2=c^2, where A and B are the legs of the triangle, and C is the hypotenuse. Let's manipulate this equation now. We are given one leg and the hypotenuse length, so the equation would be 12^2+b^2=37^2. Since we are trying to find the length of one of the legs, you subtract 12^2 from 37^2 to isolate B, and you get B^2 as 1225. You take the square root of both sides, and then you get 35 as the answer.
