The statement above is TRUE.
In mathematics, an expression refers to a definite combination of symbols, which are formed according to mathematical rules. Mathematical symbols can be used to represent numbers, variables, operations, functions, etc. Each mathematical expression usually have its order of operation.The parts of mathematical expression are called terms.
Answer:
√7x−49√x
Explanation:
First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:
√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7
... you can express √7x as √7⋅√x...
=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7
=√7⋅(√x)2−(√7)2⋅√x⋅7
... the operations squaring and taking the square root "eliminate each other"...
=√7⋅x−7⋅√x⋅7
=√7x−49√x

8 < 4 (x + 1) Use the Distributive Property
8 < 4x + 4 Subtract 4 from both sides
4 < 4x Divide both sides by 4
1 < x
The answer to this problem is x = 52/19 = 2.737... I hope...
