Answer:

25y² - 30y + 9

Step-by-step explanation:

Hello!

Solve by expanding:

  • (5y - 3)²
  • (5y - 3)(5y - 3)
  • 5y(5y - 3) - 3(5y - 3)
  • 25y² - 15y - 15y + 9
  • 25y² - 30y + 9

Remember, exponents are not distributive, meaning (5y - 3)² is not 25y² + 9.

The sum of two numbers is 53. if twice the first number minus three times the second number is 26, find both numbers.
EastWind [94]
Make an equation system based on the problem
eg. a is the first number and b is the seond number
An equation for "<span>The sum of two numbers is 53" is
</span>⇒ a + b = 53
An equation for "<span>twice the first number minus three times the second number is 26"
</span>⇒ 2a - 3b = 26
<span>
Solve the equations by elimination and subtitution method
Eliminate a to find the value of b
a + b = 53   (multiplied by 2)
2a - 3b = 26
--------------------------------------
2a + 2b = 106
2a -  3b = 26
------------------- - (substract)
       5b = 80
         b = 80/5
         b = 16

Subtitute the value of b to one of the equations
a + b = 53
a + 16 = 53
a = 53 - 16
a = 37

The numbers are 16 and 37</span>
