Divide each side by 3 :
x = -10
Answer:
the area is 145 units
Step-by-step explanation:
PART A
Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box
PART B
Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.
Answer:
hello :
-1/4y-2 1/4y+1/2(4-2y) = -1/4y-2/4y+4/2 -2/2y
= ( -1/4 -2/4 - 4/4)y +2
= (-7/4)y + 2
Answer:
see explanation
Step-by-step explanation:
Note the ratios between consecutive terms is constant, that is
- 220 ÷ 11 = 4400 ÷ - 220 = - 88000 ÷ 4400 = - 20
Thus to obtain the next term in the sequence multiply the previous term by - 20
Start with 11 and multiply by - 20
