I'm not sure by the way you layed out the question but, 2. 5(14-23)+8/2. First you have to use distributive method so 5 times 14 equals 70 and 5 times 23 equals 115 so that means it's 70-115+8/2. Then 8/2 equals 4 so 70-115+4 so then 70-115 equals negative 35. That is -35+4 so the answer is -31 or in other words negative thirty one.
I am not sure if I helped out but I tried my best
Answer:
7 1/4 yards or 7.25 yards
Step-by-step explanation:
3+3=6
5/8+5/8=1 1/4 or 1.25
6+1 1/4=7 1/4 or 7.25
Answer:
6 feet
Step-by-step explanation:
The dolphin jumps 3 feet above sea level and it starts from the opposite distance below sea level which means that would also be 3 therefore 3+3 = 6 which is your answer
X=side length of a campsite
12x(5+x)=1248 because each campsite has a length of x and there are 12 and from the top of the camp to the water is the 5 yds + a side length and LW=1248
60x+12x^2=1248
12x^2+60x-1248=0
x^2+5-14=0
(x+7)(x-2)=0
x+7=0 or x-2=0
x=-7 or x=2
x=2 because width can't be negative
the width of one campsite is 2 yds
