Fraction of girls = 1 - 3/7 = 4/7
4/7 is equivalent to 72 girls
1/7 .. .. ............. 72 / 4 = 18
Total number of children = 7/7 = 18*7 = 126 Answer
I think it’s B but don’t at me
I haven’t taken geometry in a couple years, so I hope this is right. I’m so sorry if it’s not!!
X= 91
Y= 62
Z= 45
(√3 + √11)² + (√3 - √11)²
- (a+b)² = a² + b² + 2ab
- ( a - b )² = a² + b² - 2ab
<em>Now </em><em>,</em>
(√3 + √11)² + (√3 - √11)²
(3 + 11 + 2√3√11)+ (3 +11 - 2√3√11)
14 + 2√33+ 14 - 2√33
14 + 14 = 28
Hence , The value of (√3 + √11)² + (√3 - √11)² is 28 .
Answer:
(3x-1)(x+5)
Step-by-step explanation:
Find two numbers that when they multiply, you get the third term,
which is -5 in this problem. And when they add up, you get the second term,
which is 14 in this problem.
