Answer:
9x−5
Step-by-step explanation:
Answer:
8.−2x^2+6x
9.y-1
Step-by-step explanation:
8.(−2x)(x−3)
=(−2x)(x+−3)
=(−2x)(x)+(−2x)(−3)
=−2x^2+6x
9. y^2−y
y
= y^2−y
y
=y−1
The surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²
<h3>Calculating surface area</h3>
From the question, we are to calculate the surface area of the rectangular prism
Surface area of a rectangular prism can be calculated by using the formula,
Surface area = 2(lw + lh + wh)
Where l is the length
w is the width
and h is the height
In the given diagram,
l = 21.5 mm
w = 4 mm
h = 5 mm
Putting the parameters into the equation, we get
Surface area = 2(21.5×4 + 21.5×5 + 4×5)
Surface area = 2(86 + 107.5 + 20)
Surface area = 2 × 213.5
Surface area = 427 mm²
Hence, the surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²

Answer: The secretary's salary prior to the reduction was $42,000.
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The original secretary's salary (x) multiplied by the percentage reduction in decimal form (4.5/100) must be equal to the amount of the reduction (1890)
Mathematically speaking:
x (4.5/100)= 1890
Solving for x:
x (0.045)= 1890
x = 1890/ 0.045
x = 42,000
The secretary's salary prior to the reduction was $42,000.
