Answer:
the answer is -3/2.
Step-by-step explanation:
-6-(-3) is -6+3= -3. Then -3-(-5) is -3+5=2.
Substituting values:
= 7(3)^2(5) - 32 [wait 2=-4??? Doesn’t make sense!]
= 7*9*5-32
= 315-32
= 283
Answer:
A) 3(x+6)
Step-by-step explanation:
Given,
The area of the model = (6x+18)
If the dimensions of the model are, x unit × y unit,
Then,
xy = 6x + 18
If x = 3, y = x + 6
3(x+6) = 3x + 18 ( by distributive property )
∴ Option A doesn't represent the dimensions of the model,
If x = 6, y = x + 3
6(x+3) = 6x + 18
∴ Option B represents the dimensions of the model,
If x = 0.5, y = 12x+36
0.5(12x+36) = 6x + 18
∴ Option C represents the dimensions of the model,
If x = 0.25, y = 24x + 72
0.25(24x+72) = 6x+18
∴ Option D represents the dimensions of the model,
Answer: 3.57 years
Step-by-step explanation:
Based on the question given, the interest is the difference between the amount and the principal which will be:
= $19800 - $16800
= $3000
The formula for Simple interest is given as:
Interest = Principal × Rate × Time
3000 = 16800 × 5% × Time
3000 = 16800 × 0.05 × Time
3000 = 840 × Time
Time = 3000 / 840
Time = 3.57
The time taken to grow the investment is 3.57 years
Answer:
40%
Step-by-step explanation:
Because you want to know the total percent the price increased so you add the amounts. 30% plus 10% makes 40%
