Help ASAP please ! Explain too for brainlist

Ok so im not the best at explaining but its worth a shot

C)25

Step-by-step explanation:

we already know that the formula to find area is

A=l*w

and that every square is 1 square unit.

So in the first part on the far left, you count down 8 and over 2 to find how many total squares are shaded. This is the length and width of that one part  so you multiply 8*2 to get 16.

In the next part, you should count starting at -1 over to 5 to get 6. It only has a width of 1 so 6*1 is still 6.

In the last part you start counting at -3 and count down to -6 and this gives you 3. It is 1 unit wide so 3*1 is 3.

Add 16+6+3 together because that is the combined area of the 3 parts and we get 25

Like i said im definitely, by no means, the best at explaining but if this helped even a little that's awesome, if you have any particular questions i can try to answer them in the comments

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
