Answer:
310
Step-by-step explanation:
1.75×39=68.25
241.75+68.25=310
Let's start with deleting +3d and -3d (because they have opposite signs)
8d-8 = 3d
Move unknown term (3d) to the left of equal with changed sign and known term (-8) to the right of equal with chenged sign.
8d-3d = 8
5d = 8
Divide both for 5
5d/5 = 8/5
d = 8/5
Answer:
(6,8)
Step-by-step explanation:
6 to the left and 8 up
Total possibilities would be:
(1,1)(1,2)(1,3)(1,4)(1,5)(1,6)
(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)
(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)
(4,1)(4,2)(4,3)(4,4)(4,5)(4,6)
(5,1)(5,2)(5,3)(5,4)(5,5)(5,6)
(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)
You want 5 on at-least one, so mark 5th column & 5th raw.
There are 6 in both lines with 1 common = (5,5)
In short, Your Answer would be 11
Hope this helps!
<span>2w(4w^2 - 2w) + 3w(-2w^2 + 8w)
First distribute 2w and 3w(you do this by multiplying them to all values inside the parentheses):
</span>8w^3 - 4w^2 - 6w^3 + 24w^2
Now simplify by adding/subtracting like terms:
8w^3 - 6w^3 = 2w^3
-4w^2 + 24w^2 = 20w^2
So we have:
2w^3 + 20w^2
