A and D , that is, 5∛2x and -3∛2x are sets of the radical expressions listed that could be considered like terms. This can be obtained by understanding what like radicals are.

<h3>Which sets of the radical expressions listed could be considered like terms as written?</h3>
  • Radical expression: Radical expression is an equation that has a variable in a radicand (expression under the root) or has a variable with a rational exponent.

For example, √128, √16

  • Like radicals: Radicals that have the same root number and radicand (expression under the root)

For example, 2√x and 5√x are like terms.

Here in the question radical expressions are given,

  • 5∛2x
  • -4x∛2
  • 5√2x
  • -3∛2x
  • 5x√2x

By definition of like radicals we get that 5∛2x and -3∛2x are like terms since root number and radicand are same, that is, root number is 3 and radicand is 2x.

Hence A and D , that is, 5∛2x and -3∛2x are sets of the radical expressions listed that could be considered like terms.

Find the value of x so that the function has the given value. <br> q(x)=12x−3; q(x)=−4
Anna [14]

Answer:

-  \frac{1}{ 12}

Step-by-step explanation:

since q(x)=-4

substitute

hence

-4=12x-3

take -3 to the other side where it becomes positive

therefore

-1=12x

divide by 12

Dan invests £18790 into his bank account. He receives 5,3% per year simple
earnstyle [38]

Answer:

697109 pennies

Step-by-step explanation:

First, you use the formula A = P (1 + rt).

R= rate which is 5.3%

T= time which is 7 years.

P is the principle which is 18790

A= is the answer

so first you multiply 7*5.3% which you get 0.371

then you multiply that with 18790 which then you get 6971.09

if you want pennies you multiply it with 100 to get 697109
