For this case we must simplify the following expression:

13x + 7y-2x + 6a

To simplify, we must add similar terms, that is:

13x-2x + 7y + 6a

Remember that different signs are subtracted and the sign of the major is placed. So:

13x-2x + 7y + 6a = 11x + 7y + 6a

Answer:

11x + 7y + 6a

Write the quadratic equation whose roots are 1 and −5, and whose leading coefficient is 4.
jarptica [38.1K]

Answer:

Standard Form: y = 4(x-1)(x+5)

Step-by-step explanation:

4 is the leading coefficient, so it should go in front. When making a standard quadratic equation, you must do the opposite for each of the roots (negative to positive, positive to negative.)

if you’re asking for a general form quadratic equation, then sorry, I am unable to help you with that :(

How may square roots does it to take to get a square root of the square root?
Xelga [282]

If you want to take a square root of a square root you will need 2 squares roots,


For example, i want the square root of the square root of 16.


I'll take it first: √16 = 4 and again, √4 = 2


So, the square root of the square root of 16 is 2.


But you can also make a root with index 4.


\sqrt[4]{16}=2


Because if you do 2.2.2.2 you will take 16.

Find m angle A
stepan [7]

Answer:

  D.  14°

Step-by-step explanation:

The Law of Sines tells you sides are in proportion to the sine of the opposite angle:

  sin(A)/BC = sin(B)/AC

  sin(A) = BC/AC·sin(B)

  A = arcsin(BC/AC·sin(B)) = arcsin(7/28·sin(75°)) ≈ 13.974° ≈ 14°

One side is 8 cm
musickatia [10]

Answer:

The mass of the cubic granite block  is 1408 g .

Step-by-step explanation:

Formula

Volume of a cube = a³

Where a is the side of the cube .

Density = \frac{Mass}{Volume}

As given

one side of the cube is 8 cm .

(The figure is shown below.)

Thus

Put in the formula

Volume of a cubic granite block  =  8 × 8 × 8

                                                       = 512 cm³

As given

The density of cube is 2.75 g/cm³.

Put in the formula

2.75 = \frac{Mass}{512}

Mass = 2.75 × 512

Mass = 1408 g

Therefore the mass of the cubic granite block is 1408 g .

594 7/25 +89 37/100=
bonufazy [111]

Hey there!☺

Answer:\boxed{683\frac{13}{20}}

Explanation:

594\frac{7}{25}+89\frac{37}{100}

To solve, we will need to evaluate:

594\frac{7}{25}+89\frac{37}{100}=\frac{13673}{20}

We're not done yet because we need to simplify 13673/20:

\frac{13673}{20}=683\frac{13}{20}

Hope this helps!☺
