Answer:
77 ft²
Step-by-step explanation:
Given that:
Surface Area of larger pyramid = 539 ft²
Scale factor of the smaller pyramid = 1/7
Tbe surface area of the smaller pyramid will be :
Scale factor * surface area
1/7 * 539ft²
= 539 ft² / 7
= 77 ft²
Step-by-step explanation:
3a²-7a−6
Factor the expression by grouping. First, the expression needs to be rewritten as 3a
2
+pa+qa−6. To find p and q, set up a system to be solved.
p+q=−7
pq=3(−6)=−18
Since pq is negative, p and q have the opposite signs. Since p+q is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product −18.
1,−18
2,−9
3,−6
Calculate the sum for each pair.
1−18=−17
2−9=−7
3−6=−3
The solution is the pair that gives sum −7.
p=−9
q=2
Rewrite 3a
2−7a−6 as (3a
2−9a)+(2a−6).
(3a 2−9a)+(2a−6)
Factor out 3a in the first and 2 in the second group.
3a(a−3)+2(a−3)
Factor out common term a−3 by using distributive property.
(a−3)(3a+2)
The number of cars, vans and trucks rented are;
Number of Cars = 4 cars
Number of vans = 36 vans
Number of trucks = 108 trucks
<h3>How to solve Algebra Word Problems?</h3>
We are given;
Total number of vehicles = 155 vehicles
Let number of cars be x.
Thus, since Nine times as many cars were rented as vans, we have;
Number of vans rented = 9x
Now, three times as many vans were rented as trucks. Thus;
The number of trucks rented during one month = 3(9x)
Thus;
x + 9x + 27x = 155
37x = 155
x ≈ 4 cars
Number of vans = 9 * 4 = 36 vans
Number of trucks = 3 * 36 = 108 trucks
