Answer:
76w + 17
Step-by-step explanation:
7 ( 5 + 4w ) + 6 ( 8w - 3 )
= 7 ( 5 ) + 7 ( 4w ) + 6 ( 8w ) - 6 ( 3 )
= 35 + 28w + 48w - 18
= 28w + 48w + 35 - 18
= 76w + 17
Answer:
44
Step-by-step explanation:
the mode of a set of data is the value that occurs most often, in this case it is 44
When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).
You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.
Therefore:
P(sum is even) = 2 / 4 = 0.5
Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.
Answer:
(x+3)(x+1)
Step-by-step explanation:
Think of using FOIL
First Outer Inner Last
What can you multiply to get to 3 and add up to 4
perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches
