What is the following sum? 4 (RootIndex 5 StartRoot x squared y EndRoot) + 3 (RootIndex 5 StartRoot x squared y EndRoot) 7 (RootIndex 10 StartRoot x squared y EndRoot) 7 (RootIndex 10 StartRoot x Superscript 4 Baseline y squared EndRoot) 7 (RootIndex 5 StartRoot x squared y EndRoot) 7 (RootIndex 5 StartRoot x Superscript 4 Baseline y squared EndRoot)

The sum of the expression; 4 (RootIndex 5 StartRoot x squared y EndRoot) + 3 (RootIndex 5 StartRoot x squared y EndRoot) is; 7 ⁵√x²y.

The given expression 4 (RootIndex 5 StartRoot x squared y EndRoot) + 3 (RootIndex 5 StartRoot x squared y EndRoot) can be written mathematically as;

By observation, we can conclude that ⁵√x²y is a common factor; so that we have;

Ultimately, the sum is; 7 ⁵√x²y.

Hence, is equivalent to

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

pls mark as brainliest.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
