Answer:
Area of 1 Right angle triangle= 1/2* 3*4= 6
Area of both triangle= 6*2= 12
Area of rectangle= 8*5= 40
Area of Both rectangles= 40*2= 80
Total surface area= (12*2)+ 80= 24+80= 104
Answer:
13. 4(x+3) 15. 5(x+7) 17. cannot be factored 19. 3(2x-3) 21. 9(8-2x)
23. 50(2x + 3) 25.4(x+9)
Step-by-step explanation:
Hope this helps
The answer is b=2
cuz (x-4)(x+2) multiplies
into x^2-2x-8
