Answer:
4x²y² + 20xy² + 25y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 2xy ; b = 5y
(2xy +5y)² = (2xy)² + 2*(2xy) * (5y) +(5y)²
= 2²x²y² + 2* 2* 5 * x*y*y + 5²*y²
=4x²y² + 20xy² + 25y²
Answer:
x = 73
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
(180 - x) + (90 - x) = 124
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 270 - 2x = 124
- Subtract 270 on both sides: -2x = -146
- Divide -2 on both sides: x = 73
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: (180 - 73) + (90 - 73) = 124
- Subtract: 107 + 17 = 124
- Add: 124 = 124
Answer:
D
Step-by-step explanation:
Because the term 7x^3 is to the third power, the curve moves like x^3. This means that as x approaches infinity and -infinity, it approaches infinity and -infinity respectively. The answer is D.
The prime factorization of 240 is 2 x 2 x 2 x 2 x 3 x 5
The easy way I was taught how to find the product of primes is: Draw a vertical line. On the left write your number. On the right, write the smallest Prime number that is a factor of this number (i.e ask, does it divide by 2? If the answer is no, then ask does it divide by 3, 5, 7 etc etc until you find a number that does). Then divide the number on the left by the number on the right and write it under the number on the left. Repeat this process until the number on the left is equal to the number on the right (i.e. a prime number).
eg, for 240:
240 | 2
120 | 2
60 | 2
30 | 2
15 | 3
5 | 5
