Answer:
So the value of s = 7
cm
Step-by-step explanation:
We know that, Area of a triangle = 1/2 * b * h
So, base = 24 cm
height = s
Area = 1/2 * b * h
=>84 = 1/2 * 24 * h
=>84 = 12 * h
=>84 / 12 = h
=> 7 = h (in cm)

Answer:
Therefore Neither option A nor option B will allow them to meet their goal....
Step-by-step explanation:
The Polleys need to save $6,000 over 12 months.
After 7 months they discovered that they have saved $ 3,100 but in actual they have to save $3,500. It means $400 are short. Therefore for the remaining months they must save $6000-$3100 = $2900. They have to save 2900/5 = $580 each month.
According to the Option A The original amount was $500, in 5 months they will save 500*5 =$2500. They need total of $2900, which means $400 are short.
According to the Option B Increase savings each month by $100 from their original plan makes a total amount of $3000. This amount exceeds their goal.
Therefore Neither option A nor option B will allow them to meet their goal....
Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
Subtract (20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
Open bracket
20c + 15r + 75p + 50e - 12c - 22r - 65p - 70e
Collect like terms
= 20c - 12c + 15r - 22r + 75p - 65p + 50e - 70e
= 8c - 7r + 10p - 20e
