Answer:

B

Step-by-step explanation:

so first you got to solve the expression  so -2.5(-1-2n)-1.5

−2.5(1−2n)−1.5n

Use the distributive property to multiply −2.5 by 1−2n.

−2.5+5n−1.5n

Combine 5n and −1.5n to get 3.5n.

your answer is  −2.5+3.5n  

if this is wrong then probably

solve the other expressions to see if u get the same answer

Determine the area of the composite figure to the nearest whole number.
Arada [10]
So this is a two step process, first you must find the area of the rectangle, then find the area of the semicircle.

So to find the area of a rectangle, you use: Length*Height=Area
In this case that would be: 7*2=14cm

Next you find the area of the semicircle, to do this you first find the area of the circle (Pi*r^2) then divide it by 2.

The diameter of the circle is 4 because: 7-2-1=4cm
Next divide that by 2 so that you get the radius: 4/2=2cm
Not you can plug that into the equation to get the area of the circle: Pi*2^2<span>≈13cm^2
Next divide it by 2 so that you get the area of the semicircle:13/2</span><span><span>≈</span>6cm^2

At this point you can add the area of the semicircle to the area of the rectangle: 14+6=20cm^2

So your final answer is 20cm^2!
