Is B. 224 in^2
2•(4•10+3•5)+3•10•2+(9•3)+(3•5)+(3•4)=224
Answer:
3x + 3 = 26 or 2x - 3 + 2 = 26
Step-by-step explanation:
N = Nate
M = Maya
M = 2x - 3
N = x
2x -3 + x = 26
3x + 3 = 26
This will help you find the value of x, which is Nate's value. Then in return will help you find the value of Maya's.

Answer:
x = 20
Step-by-step explanation:
To do this question, you can use the pythagorean theorem. c is your hypotenuse, a is the unknown side length and b is the known side length.
a^2+b^2=c^2
x^2+15^2=25^2
x^2=225=625
x^2=400
(x^2)^(1/2)=400^(1/2)
x = 20
Answer:
#3:8n-4
Step-by-step explanation:
combine like terms
3n+n=4n
-7+5=-2
4n-2
multiply that by 2 to get the perimeter, which is 8n-4
The solution of the quadratic equation is x = 0 or x = 6 ⇒ 4th answer
Step-by-step explanation:
The form of the quadratic equation is ax² + bx + c = 0, where
- a is the coefficient of x²
- b is the coefficient of x
- c is the numerical term
The quadratic equations has two roots, to find them factorize it into two factors and equate each factor by zero
∵ 3x = 0.5 x²
- Subtract 3x from both sides
∴ 0 = 0.5x² - 3x
- Multiply both sides by 2 to make the coefficient of x² integer
∴ 0 = x² - 6x
- Switch the two sides
∴ x² - 6x = 0
- Factorize it by taking x as a common factor
∴ x(x - 6) = 0
- Equate each factor by 0
∴ x = 0 → 1st root
∴ x - 6 = 0
- Add 6 to both sides
∴ x = 6 → 2nd root
∴ The roots of the equation are 0 or 6
The solution of the quadratic equation is x = 0 or x = 6
