312* 17.5= 5460.00
134*19=2546
2546+5460= $8,006.00
Answer:
2/24
Step-by-step explanation:
the picture in the attached figure
Step 1
Find the perimeter of the scaled-down model of a walkway (Quadrilateral ABCD)

Step 2
Find the scale factor
if Quadrilateral ABCD is similar to Quadrilateral EFGH
then


Step 3
Find the perimeter of the actual walkway (Quadrilateral EFGH)



therefore
the answer is

Rearrange the equation by writing
x² + x - 90 = 0
x² + x = 90
x² + x + 1/4 = 90 + 1/4
Recall that (a + b)² = a² + 2ab + b². Then
x² + 2 • x/2 + (1/2)² = 361/4
(x + 1/2)² = 361/4
x + 1/2 = ± √(361/4)
x = -1/2 ± 19/2
x = 9 or x = -10
The denominator in each term of the series is a square number, but neither

nor

are squares. So none of (1), (2), and (4) can be correct. The answer must be (3).
