Answer:

x=-3.5 or -3 1/2

Step-by-step explanation:

2(x+3)+7x=3(x-2)-9

2x+6+7x=3x-6-9

9x+6=3x-15

2) 7/4×(22–x) =0

soln

= 7/4×(22 –x) =0

= 1.75 ×22 –x =0

= x=38.5

9) 15x² /7 =8x²/5

soln

= 15x²×8x²=7×5

=120x^4 = 35

= x^4 =120–35

x^4 =85

6) 9x²/4–4=0

soln

=9x²/4–4=0

=2.25–4=0

=4–2.25=0

=1.75

Find the perimeter of the figure

SashulF [63]

To solve this, find the rest of the sides:

The other sides are:

1. 24 - 8 = 16
2. 23 - 9 = 14

Next, just add it up:

24 + 9 + 16 + 14 + 8 + 23 = 33 + 30 + 31 = 94
