Answer:
L = 324 cm²
S = 359.1 cm²
Step-by-step explanation:
Lateral surface area of a triangular prism is given by,
Lateral surface area = Perimeter of the triangular base × Height
= (9 + 9 + 9)×12
= 27 × 12
= 324 cm²
Surface area area of the triangular prism = Lateral area of the prism + Area of the triangular bases
= 324 + 
= 324 + 
= 324 + 35.1
= 359.1 cm²
Answer:
x=5
Step-by-step explanation:
1) Group like terms which will then make the equation 4x-2(x-5)=5x-5
2) Expand the equation (multiply) which will make it 4x-2x+10=5x-5
3) Add similar elements; 2x+10=5x-5
4) Subtract 10 from both sides; 2x=5x-15
5) Subtract 5x from both sides; -3x=-15
6) Divide by 3; x=5

Answer:
Step-by-step explanation:
Part A
The discount offered is 30%. If the original price of a sweater is $40, then the discount on the sweater is
30/100 × 40 = $12
The cost of the sweater after the discount is
40 - 12 = $28
Part B
The discount on the shirts was 30%. The amount taken off the shirt is
30/100 × 63 = $18.9
The original cost of the three shirts is
63 - 18.9 = $44.1
Since the shirts are of the same price,the original cost of each shirt is
44.1/3 = $14.7
Part C
Each employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, then the additional amount taken off is
10/100 × 40 = $4
The amount that the employee would pay is
40 - 4 = $36
Answer:
3
Step-by-step explanation:
a^2+b^2=9
(a+b)^2=9
finding the square root on both sides of the equation
a+b=3
