STEP 1
Equation at the end of step
((14 • (x2)) - 7xy) - (3•72y2)
Equation at the end of step 2
((2•7x2) - 7xy) - (3•72y2)
STEP 3
STEP 4
Pulling out like terms
4.1 Pull out like factors :
14x2 - 7xy - 147y2 = 7 • (2x2 - xy - 21y2)
Trying to factor a multi variable polynomial :
4.2 Factoring 2x2 - xy - 21y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x - 7y)•(x + 3y)
So you need to mutpies it and then never forget that 0.23
chance of getting red is 8/25
1,000/25 = 40
8 x 40 = 320
ANSWER : D. 320
Answer:
36
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Simplifying the radicals in the expression
= 
= 
× = 2
= 
= 
× = 4
Thus
4 + 7
= 4 × 2 + 7 × 4
= 8 + 28
= 36
