Using the distributive property you would multiply 15 by each term inside the parentheses:
15 times x = 15x
15 times 2 = 30
The equivalent expression would be 15x + 30
Difference is asking you to subtract:
-4 - (-5)
Note that when subtracting, when 2 subtraction signs are in a row, it turns into an addition sign:
-4 + 5
If we rearrange this:
5 - 4
1

Answer:
an = 6n -2
Or
an+1 = an +6
Step-by-step explanation:
to go from 4 to 10 we add 6 tiles
to go from 10 to 16 we add 6 tiles
We add 6 tiles each time
an = a1 + d(n-1) where an is the value of the nth term a1 is the first term d is the common factor and n is the term number
an = 4 + 6( n-1)
an = 4 + 6n -6
an = 6n -2
Or
an+1 = an +6
Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
