Problem: 4+x=15
- Subtract 4 from both sides
4+x-4=15-4
- Refine
x = 11
Answer: 4,320 inches cubed.
Step-by-step explanation:
step 1----- Volume of 1 canvas box
Volume of solid for a rectangular box = Length x width xHeight
where Length= 12inches,
Width= 10 inches
Height= 12 inches
Volume of a Canvas box= 12 X 10 X 12= 1440 inches cubed
Step 2== Volume of 3 canvas boxes
1 canvas box = 1440 inches cubed
therefore 3 canvas boxes =
1440 x 3= 4320 inches cubed.
Answer:
-8/23
Step-by-step explanation:
3x/(5x+2) = - 4
3x = - 4(5x + 2)
3x = -20x - 8
23x = - 8
x = - 8/23
Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A = × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
