Evaluate x(y-z)2 for =-1,y=5,and z=

Nata [24]

Answer:

The value of $x(y-z)^2$ is -16.

Step-by-step explanation:

We need to evaluate $x(y-z)^2$ for x = -1, y = 5 and let us assume that z = 1

It can be simply done by putting the values of x,y and z in the given expression.

$x(y-z)^2=(-1)(5-1)^2\\\\=-1(4)^2$

We know that the value of 4² = 16

So,

$x(y-z)^2=16\times -1\\\\=-16$

So, the value of $x(y-z)^2$ is -16.

What is the square root 6n carried to the power of 2/3 in radical form

BaLLatris [955]

Answer: $\sqrt[3]{6n}$

Step-by-step explanation:

We have the following expression:

$(\sqrt{6n})^{\frac{2}{3}}$

Which can be written as follows:

$((6n)^{\frac{1}{2}})^{\frac{2}{3}}$

Multiplying the exponents:

$(6n)^{\frac{1}{3}}$

Writing in radical form we finally have the result:

$\sqrt[3]{6n}$

QUESTION: Josephine put a frame round his picture which measured 36 cm by 34 cm. A margin 4cm wide was left all the way round. W

Mandarinka [93]

36x34= 1224cm²
(36-4)x(34-4)= 32x30= 960cm²

Area of frame= 1224
Area of picture inside frame= 960
So border = 1224-960= 264

ANSWER = 264cm²

The sum of three consecutive numbers is 46. Find the

Citrus2011 [14]

Let the three consecutive number be x,x+1 and x+2.

It is given sum of three consecutive numbers is 46.

So,x+x+1+x+2=46

3x+3=46.

Subtracting 3 both sides

3x=46-3

3x=43.

x= $\frac{43}{3}.$

Since $\frac{43}{3}.$ is not an integer there is no true answer to this problem.
