Answer:
D: 10x + 5y
Step-by-step explanation:
If we substituted the x and y values in all of these equations, these are the equations and sums we would get:
A: 18 + 54 = 72
B: 30 + 90 = 120
C: 36 + 81 = 117
D: 60 + 45 = 105
Because we now know all of the sums for these equations, we can rule out A, B, and C because they don't have the correct answer that we got when we evaluated the expression which was 105. The only possible option would be D.
(sorry if this is confusing)
Answer:The area method, also sometimes called the box method, is an alternative to the standard algorithmic method (see below) for long multiplication.The standard algorithm is generally a faster method but, unlike the area method, it does not promote understanding or encourage the development of mathematical thinking.please mark as brainliest
Step-by-step explanation:
It's 5 units right and 2 units down. you just need to choose one point (any point) and keep moving it until it matches the translated shape :)
Answer:
x = 9
Step-by-step explanation:
-2x = 18 - 4x
-2x + 4x = 18
2x = 18
x = 18/2
x = 9
F(x)=-2if-1
f’(x)=d/dx (-2fi-1)
F’(x)=0
