reemmber that a(b+c)=ab+ac
4(6m+3)=4(6m)+4(3)=24m+12




A. 24m+12 and 12(2m+1)

The painting shown at the right has an area of 220. What is the value of x?
tangare [24]

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

URGENT!!!!!<br> With workings
Aneli [31]
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

What would be the volume of the cone that has the same measurement as the cylinder above in the pic
fomenos

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

Volume of cone will be ~

\fbox \colorbox{black}{ \colorbox{white}{volume} \:  \:  \:   \:   \: \colorbox{white}{=}  \:  \:   \:   + \colorbox{white}{462 \: cm³ }}

\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}

Let's find the volume of cone with ~

  • radius (r) = 7 cm

  • height (h) = 9 cm

And as we know, volume of cone is equal to ~

  • \dfrac{1}{3}\pi  {r}^{2} h

now, let's plug in the values and find the volume ~

  • \dfrac{1}{ \cancel{3}  }\times  \dfrac{22}{\cancel{7}}  \times \cancel{7 }\times 7 \times \cancel{9}

  • 1 \times 22 \times 7 \times 3

  • 462 \:  \:  {cm}^{3}

Volume of cone is 462 cm³ = 462 ml

Translate this phrase into an algebraic expression.
Levart [38]

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
