Answer:
(2w-1)/5+w+2=2w
We simplify the equation to the form, which is simple to understand
(2w-1)/5+w+2=2w
Reorder the terms in parentheses
( + 0.4w-0.2)+w+2=2w
Remove unnecessary parentheses
+ 0.4w-0.2+w+2=2w
We move all terms containing w to the left and all other terms to the right.
+ 0.4w+1w-2w=0.2-2
We simplify left and right side of the equation.
-0.6w=-1.8
We divide both sides of the equation by -0.6 to get w.
w=3
Step-by-step explanation:
Answer:
multiply both sides by 4
Step-by-step explanation:
Answer: 1,162.9 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a square pyramid: 1/3 x base area x height
Where
base area = base side length ^2
Replacing with the value given:
Base area = 15.9^2
base area : 252.81 cm2
Back with the volume formula:
V = 1/3 x base area x height
Replacing with the values given and solving for V (volume)
V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters
Feel free to ask for more if needed or if you did not understand something.
Answer:
The first one is missing (d - 9) so it would be 5(d -9) or when you factor it out 5d - 45
In the second one (d + 7) is missing so it will be 8d(d + 7) so if you factor that out you will receive 8d^2 + 56
Step-by-step explanation:
3d^2 + 18d -21 =(3d -3)( d + 7)
3d^2 -30d +27 =(3d -3)(d - 9)
