Answer:
Richard's cumulative GPA = 2.5
Step-by-step explanation:
Richard's cumulative GPA for 3 semesters was 2.0 for 42 credits.
Average = 2
Total credits = 42
Average = sum of terms/total no of terms
2 = sum of terms/42
sum of terms = 84 ....(1)
His fourth semester GPA was 4.0 for 14 course units
Average = 4
Total credits = 14
sum of terms = 56 .....(2)
Average for 4 semesters,

Hence, Richard's cumulative GPA for all 4 semesters is 2.5.
Answer:
9.05
Step-by-step explanation:
make gallons into quarts
quar prefix in many languages means 4
1 gallon is 4 quarts
3 gallons is 4 times 3 -> 12 quarts
just by seeing 108 and 12 the answer will be around 9
108.90 ÷ 12 = 9.05
It’s standard form
standard form is generally ax^2+bx+c
Answer: Length = 10 inches, Width = 7 inches
Step-by-step explanation:
Area = L x W
Area = 70 square inches
Length = 2W - 4
70 = 2w - 4 x w
70 = 2w^2 - 4w
2w^2 - 4w = 70
2w^2 - 4w - 70 = 0
Factor
(2w + 10)(w-7) = 0
w = 7
70 = L x 7
L = 10
