Answer:
9.76
Step-by-step explanation:
area of a rectangle = length * breadth
length = (2x + 3)
breadth = x
given area is 220 sq. inches.
thus,
220 = x * (2x+3)
220 = 2x² +3x
2x² + 3x -220 = 0
x = (-b + √ ( b²-4ac) ) ÷ 2a
x = ( -3 + √ ( 3² - 4*2*220) ) ÷ 2*2
x =9.76
The equation that is equivalent to 15-7x=14 is x=7
There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me
i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)
THE ANSWER IS 68.9 CM

Volume of cone is 462 cm³ = 462 ml
Answer:
(n*19)-4
Step-by-step explanation:
A product is the result of multiplication, so the product of a number (represented as n) and 19 would be n*19. Put these in parentheses, so that it remains organized and you don't become confused later.
Then 4 less would simply mean you subtract 4 from the product of n and 19.
(n*19)-4
