1a.) ??
1b.) SA = (2.24*1.5)*4+(3^2)
2.) (6*12)+(3.6*4)2
6*12 because the length of the sides of the three inner rectangles are equal to 6 and 4*3, which is 12.
3.6*4*2 because if you cut the triangles and shape them into rectangles, you get side lengths of 3.6 and 4, and then you multiply by 2, to account for the other triangle.
3a/b.)??
Answer:
x = 8
Step-by-step explanation:
4x + 112 = 9x + 72
-112 -112
4x = 9x - 40
-9x -9x
-5x = -40
----- --------
-5 -5
x = 8
I believe George will have 249.75 dollars.
If he earns 9.5% annually, you would have to multiple .095 which is 9.5% by 150 to get 14.25. Once you have that you need to multiply it by 7 for the 7 years that it’s in the account to get 99.75, next add that to 150 to get the answer
150 x .095 = 14.25
14.25 x 7 = 99.75
99.75 + 150 = 249.75
