Answer:

D is the answer.

4x - 9 = 0  \\ 4x = 9 \\ x =  \frac{9}{4}  \\ or \\ 4x + 9 = 0 \\ 4x =  - 9 \\ x =  -  \frac{9}{4}

The number square root of 3 goes on forever with no repeating pattern therefore it is rational?
vova2212 [387]

Answer:

False

Step-by-step explanation:

A number that can expressed as \frac{p}{q},

Where, p and q are integers such that q ≠ 0, is called a rational number.

Also, a decimal number with repeating pattern is a rational number,

( for eg : 0.333.... = \frac{3}{9} )

Since,

√3 = 1.73205080757.....

∴ There is no repeating pattern

Thus, √3 is not a rational number.

Given statement is FALSE.

A cube has a lateral surface area of 64sq m find the total surface area of the cube
Roman55 [17]

Answer:

384 square meters.

Step-by-step explanation:

Given that a cube has a lateral surface area of 64 square meters, to find the total surface area of the cube, the following calculation must be performed, knowing that the formula to calculate the area of a cube is to multiply by 6 (the number of sides of the cube) the area of one of its sides:

A x 6 = X

64 x 6 = X

384 = X

Thus, the area of the cube is 384 square meters.
