Answer:
Tom is incorrect.
Step-by-step explanation:
A square by definition implies that all sides of the square are the same measurements. In the case of finding the area, A = s². Tom, however, solved it as A = 2s.
In this case:
Area of square = s² = 11² = 121 ft²
121 ft² is the correct measurement.

Answer:
The ordered pair solution is (-2, 8)
Step-by-step explanation:
y = -4x ------ equation 1
y = 2x + 12 ---- equation 2
We solve for x by substitution;
Substituting the value of y into equation 2;
y = 2x + 12
-4x = 2x + 12
-4x -2x = 12
-6x = 12
Divide by -6
x = 12/(-6)
x = -2
From equation 1;
y = -4x
Substituting the value of x;
y = -4×(-2)
y = 8.
PROOF;
y = -4x
8 = -4*(-2)
8 = 8
Answer:
x < - 5/9
Step-by-step explanation:
5(x-3)-6(x-2)>8x+2
5x-15-6x+12>8x+2
-x3>8x+2
-x-8x>2+3
-9x>5
x<-5/9
Answer:
Enrollment at walnut junior = 142
Enrollment at walnut high = 710
Step-by-step explanation:
Let :
Enrollment at walnut junior = x
Enrollment at walnut high = 5x
Total enrollment in both schools = 852
Mathematically ;
x + 5x = 852
6x = 852
x = 142
5x = 142 * 5 = 710
Hence,
Enrollment at walnut junior = 142
Enrollment at walnut high = 710
