21x 3 times 7 would give you 21 and then add the x
Answer:
8
Step-by-step explanation:
Given the expression
4t^6-r^10 we are to factorize in the form;
(2t^x+r^y)(2t^x-r^y)
First we need to factorize (2t^x+r^y)(2t^x-r^y)

Compare 

Get y;

Hence the sum of x and y is 8

Answer:
3/5 , 7/2 , 3 1/2
Step-by-step explanation:
<h2>
Step 1 -</h2>
Two Plus One - Third
2 + 
Make Both Fractions-
+ 
Make Same Denominator ( Bottom # Of Fraction )-
*
= 
New Equation-
+
= 
<h2 /><h2>Step 2-</h2>
Seven - Thirds Divided By Two-Thirds.

Divide In Parts-
7 / 2 = 3.5
