Answer:
x^2 +14x+49
Step-by-step explanation:
Area = length * width
= ( x+7) * ( x+7)
FOIL
first: x^2
outer: 7x
inner: 7x
last: 7*7 = 49
Add them together
x^2 +7x+7x + 49
Combine like terms
x^2 +14x+49

Answer:
C. 1/4
Step-by-step explanation:
The probability of landing tails is 50%, since coins are two sided.
If a cube has 6 numbers, the probability of getting an even number is also 50% since 2,4,and 6 are even while 1,3, and 5 are odd.
The probability of getting both would be 25% (I multiplied 1/2 by 1/2)
Area is 50 m^2
5 x 3 = 15
7 x 5 = 35
35 + 15 = 50 m^2
