Answer:
3(x + 9)(x + 9)
Step-by-step explanation:
- 3x^2 + 54x + 243
- 3(x^2 + 18x + 81)
a + b = 18
a + b = 81
a= = 9, b = 9
3. 3(x + 9)(x + 9)
Answer: 7
Step-by-step explanation:
Since squares have the same side lengths
then you need to find a number that multiplies twice that equals 49
7*7 = 49
X = 2 + 4y....with x being the larger number and y being the smaller number
OR
y = 2 + 4x....with y being the larger number and x being the smaller number
