Answer:
a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
98 square feet
Step-by-step explanation:
The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
The correct area =
15(2x + 7).
= 30x + 105 square feet
The error in Shawn’s expression is
= 15(2x + 7)
= 30x + 7 square feet
Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
30x + 105 square feet - 30x + 7 square feet
= 30x + 105 - (30x + 7)
= 30x - 30x + 105 - 7
= 98 square feet
Yes
slope = (26 - 13) / (16-8) = 13/8
y = mx + b passing (8,13)
13 = 13/8(8) + b
13 = 13 + b
so b = 13-13 = 0
equation y = 13/8x

Step-by-step explanation:
It is the closest to the answer and you would get closest to that even without really needing to work anything out
N=55
A^2 + B^2 = C^2
48^2 + B^2 = 73^2
2304 + B^2 = 5329
-2304 -2304
B^2 = 3025
Sqrt B^2= sqrt 3025
B= 55
