The answer is 29/21. 4/6 + 5/7 = 29/21. so theres your answer
Step-by-step explanation:
4x-2y = 9 ...1
2x-y = -6 ...2
if ...2 × 2
4x-2y = -12
9 is not equal to -12
Answer:
C) To square a number, multiply the number by itself.
Step-by-step explanation:
A) is incorrect because square roots are made by multiplying the number to itself.
2 × 2 is the same as 2²
3 × 3 is the same as 3²
4 × 4 is the same as 4²
2² = 4
3² = 9
4² = 16
B) is incorrect because the inverse of squaring is finding the square root.
2² inverse is √4
3² inverse is √9
4² inverse is √16
D) is incorrect because perfect squares can be odd or even
A perfect square is a number made by squaring a whole number.
4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.
Answer:
missing angle isosceles angle and side (a)
Pythagoras theorem
a²+a²=16²
a²=256/2
a=√128=11.3=11
√64= 8
√n³⁶= n¹⁸
Final answer: 8n¹⁸, or B
Remember that (n¹⁸)²= n³⁶. Therefore n⁶ is incorrect.
