One side of a square is 11 ft. Tom found that the area of his square is 22. Is Tom correct? Explain why he is correct or incorre
guapka [62]

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.

What is the ordered pair solution to the system y= -4x and y=2x+12 ??
german

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

Sunny_sXe [5.5K]

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
