A rectangular piece of tin has an area of 1056 square inches. A square of 3 inches is cut from each corner, and an open box is m
kvv77 [185]

Answer:

44 inches and 24 inches

Step-by-step explanation:

Let l,b denotes length and breadth of a rectangle.

lb=1056

A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides.

New length =l-6 inches

New breadth =b-6 inches

Height of box =3 inches

Volume of box = length × breadth × height

(l-6)(b-6)3=2052

lb-6l-6b+36=684\\6(l+b)=408\\l+b=68\\b=68-l

Put b=68-l in lb=1056

l(68-l)=1056\\l^2-68l+1056=0\\l^2-44l-24l+1056=0\\l(l-44)-24(l-44)=0\\(l-24)(l-44)=0\\l=24,44

At l=24,b=\frac{1056}{24}=44 inches

At l=44,b=\frac{1056}{44}=24 inches

A line passes through the points (7, 10) and (7, 20). Which statement is true about the line? It has a slope of zero because x 2
yaroslaw [1]

Answer:

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

Step-by-step explanation:

Points:

  • (7, 10) and (7, 20)

Slope-intercept form:

  • y= mx+b

slope is:

  • m= (y2-y1)/(x2-x1)= (20-10)/(7-7)= 10/0,

denominator of the fraction is zero, we can't divide by zero, so this line has no slope

----------

It has a slope of zero because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the numerator of a fraction cannot be zero.

  • no, numerator is not zero

It has a slope of zero because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

  • no, it has no slope

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the numerator of a fraction cannot be zero.

  • no, numerator is not zero

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

3-x=5x+21
vlada-n [284]

Answer:

<h3>\boxed{ \sf{ \bold{- 3}}}</h3>

Step-by-step explanation:

\sf{3 - x = 5x + 21}

Move 5x to left hand side and change it's sign

⇒\sf{  - x - 5x  + 3 = 21}

Move 3 to right hand side and change it's sign

⇒\sf{ - x - 5x = 21 - 3}

Collect like terms

⇒\sf{ - 6x = 21 - 3}

Subtract 3 from 21

⇒\sf{ - 6x = 18}

Divide both sides of the equation by -6

⇒\sf{ \frac{ - 6x}{ - 6}  =  \frac{18}{-6}}

Calculate

⇒\sf{x  = -3}

Hope I helped!

Best regards!!
