A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece
Karo-lina-s [1.5K]

Answer: 7 inches

Step-by-step explanation:

       If x is the first piece, and the second piece is twice as long, then the second piece is 2x.

        If the third piece is three times as long as the first piece, x, then the third piece is 3x.

       The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.

42 = x + 2x + 3x

42 = 6x

42 = 6x

7 = x

              The first piece is 7 inches long.

Alika [10]

Options:

A.) square root

B.) exponential

C.) absolute value

D.) cube root

Answer : A) square root

We know area of square having side 's' = s* s = s^2

For example

Area of square =  16 cm^2

To find side we take square root

Area = (side)^2

16 = (side)^2

Take square root on both sides

\sqrt{16}= \sqrt{side^2}

4= side

Betsy knows that the area of the rug is A square feet.

Area A = (side)^2

\sqrt{A} = side

So answer is square root.

Please help me with this problem
Naya [18.7K]

Answer:

Dasha has 52 roses

Step-by-step explanation:

Rewrite the first sentence in an equation: (D= Dasha) (A= Anna)

D=4A

Rewrite the second sentence in an equation:

A+39=D

1) Substitute A+39 as D in the first equation:

A+39=4A

2) Subtract A from both sides:

3A=39

3) Divide both sides by 3:

A=13

4) Now substitute 13 as A in the second equation:

13+39=D

5) Solve:

D=52
