Answer:

  The volume is 343 times as large.

  The length is 7 times as large.

Step-by-step explanation:

If the original cube has side length s, its volume is given by ...

  V = s³

When the side length is changed by a factor of 7, the new volume is ...

  V = (7s)³ = 7³×s³ = 343s³

The volume of the cube changes by a factor of 7³ = 343.

__

The problem statement tells you the length is 7 times as large.

vovikov84 [41]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x = 11}}}}}

Step-by-step explanation:

\sf{ - 2(3 - 2x) =  - 6x + 8(x + 2)}

Distribute -2 through the parentheses

Similarly, Distribute 8 through the parentheses

\dashrightarrow{ \sf{ - 6 + 4x =  - 6x + 8x + 16}}

Collect like terms

\dashrightarrow{ \sf{ - 6 + 4x = 2x + 16}}

Move 2x to left hand side and change it's sign

Similarly, move 6 to right hand side and change it's sign

\dashrightarrow{ \sf{4x - 2x = 16 + 6}}

Collect like terms

\dashrightarrow{ \sf{2x = 16 + 6}}

Add the numbers : 16 and 6

\dashrightarrow{ \sf{2x = 22}}

Divide both sides by 2

\dashrightarrow{ \sf{ \frac{2x}{2}  =  \frac{22}{2} }}

Calculate

\dashrightarrow{ \sf{x = 11}}

Hope I helped!

Best regards! :D

. If three angle of a quadrilateral are in the ratio 2: 3: 5 and fourth angle is 130
alexgriva [62]

Answer:

Step-by-step explanation:

So let the angles be 2x,3x,5x

∠A + ∠B + ∠C + ∠C = 360  

[Sum of all the angles of a quadrilateral ]

⇒2x+3x+5x+130=360  

⇒10x = 360 -130  

⇒x =  23

The angles are ,

∠A = 2x = 2×23 = 46

∠B = 3x = 3×23 = 69  

∠C = 5x = 5×23=115

Jeremy built an office with a floor area of 55/14 square feet. The office is rectangular in shape. If the length of the room is
Alexxandr [17]

Answer:

110/289 feet

Step-by-step explanation:

Step one:

given data

Area of the floor= 55/14 square feet.

The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet

Step two:

The expression for the area of the room is

Area= L*W

55/14= 17/2*W

55/14=17W/2

cross multiply

17W*14=55*2

289W=110

divide both sides by 289

W= 110/289 feet
