Answer:
(10, -20).
Step-by-step explanation:
y= -5x + 30
x = 10
Substitute x = 10 in the first equation:
y = -5*10 + 30
y = -50 + 30
y = -20.
So the solution is (10, -20).
The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: <span>(4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x</span>
3000 + 500 + 60 = 3560

Answer:
Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 10 m
Hight, h = 14 m
Radius, r = d/2 = 5 m
We need to find the lateral area of the cylinder. The formula for the lateral area of the cylinder is given by :
So, the lateral surface area of the cylinder is equal to 
.
Answer:x=9
Step-by-step explanation:
The square root is the opposite of squaring a number. When you square a number you times it by itself. So if you square 3 you get 3x3=9. Square root is finding what number you multiply times itself to get 9...
