The answer will be letter C
The answer is 49 because since she multiplied 5 by 7 you have to do the same to yellow marbles so 7×7 = 49
Use Hooke's law... (just kidding)
Break down each force vector into horizontal and vertical components.



The resultant force is the sum of these vectors,

and has magnitude

The closest answer is D.
<span>Understand that:
• the sum of two positive numbers is greater than either
number.
Understand that addition is the inverse of subtraction (addition
reverses subtraction and vice versa) and use this to check
results.
Respond rapidly to oral or written questions, explaining the
strategy used. For example:
• 654 add 50… Add 68 to 74…
• 7 add 12 add 9… Add 15, 6, 4, 15 and 1…
• What is the sum/total of 26 and 39? And of 13, 62 and 3?
• How many altogether are 121 and 35? And 61, 37 and 6?
• Increase 48 by 22.
• Which three numbers could have a total of 103?
Are there any others?</span>
That would be option A as the angles and sides ( the AS) have already been stated.
