4,839 sq. yd. 8 sq. ft.139 sq. in.+ 7 sq. ft. 124 sq. in

4,846 square yard and 11 square inchs

Step-by-step explanation:

(8 sq ft + 7 sq ft)= 15 sq ft

(139 sq in + 124 sq in)= 263 sq in

12 in = 1 ft so 263/12= 21ft and 11 inch

3 feet = 1 yard so 21/3= 7 yards+ 4,839=

4,846 square yard and 11 square inchs

4840 sq yd   7 sq ft   119 sq in

Step-by-step explanation:

When I add these I like to line them up vertically

4,839 sq. yd. 8 sq. ft.139 sq. in.

                  + 7 sq. ft. 124 sq. in

4839  sq. yd. 15 sq. ft. 263 sq. in.

We know 12in * 12 in = 144  in^2 = 1 ft*1ft = 1 ft^2

so 144 in ^2 = 1 ft^2

If we have more than this amount in square in, we have to reduce the square inches and move it to the square feet.

Subtract 144 in ^2 and add 1 ft^2

4839  sq. yd. 15 sq. ft. 263 sq. in.

                    + 1  sq ft    -144 sq in

4839  sq yd   16 sq ft   119 sq in

We know 3 ft * 3ft = 9 ft^2  =1yd*1yd = 1 yd^2

Subtract 9ft^2 and add 1 yd^2

If we have more than this amount in square ft, we have to reduce the square ft and move it to the square yds.

4839  sq yd  16 sq ft   119 sq in

   +1   sq yd    -9 sq ft

4840 sq yd   7 sq ft   119 sq in

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
