Answer:
A. 84 cm²
Step-by-step explanation:
Surface area of triangular prism = 2(base area) + (Perimeter)*height of prism
Base area = 6 cm² (given)
Perimeter = 12 cm
Altitude = height of prism = 6 cm
Plug in the values into the formula
Surface Area of triangular prism = 2(6) + (12)*6
= 12 + 72
= 84 cm²
The annual interest rate of her investment would be = 4%
<h3>Calculation of annual interest rate</h3>
The principal amount invested= $500
The period of investment= 4years
The interest received= $80
The interest rate= ?
To calculate the interest rate use the formula,
SI = P×T×R/100
80 = 500 × 4 ×R/100
Make R the subject of formula,
R= 80 ×100/500×4
R= 8000/2000
R= 4%
Therefore, the annual interest rate of her investment would be = 4%.

Answer:
D
Step-by-step explanation:
Distributive property: a*(b+c) = a*b + b*c
-7(8x - 3) + x = -7*8x - 3 * (-7) + x
= -56x + 21 + x {Bring the like terms together}
= -56x + x + 21 {Now, add the like terms}
= -55x + 21
