Answer:

Step-by-step explanation:

You are correct. The answer would be B. When you look at this equation, look to see where the parenthesis are located. Parenthesis mean multiply. So if we took them out, the problem would look like this:

4 × 1 × c + 1 × 7

Because the multiplication sign comes after the 4, you are multiplying the (4 + 7) by 1, not 4.

I hope this makes sense. Please let me know if you need any more help or clarification. Good luck!

A graphic designer chose a base font size and represented it as 1 on the scale. he then listed some consecutive scale sizes. two

garik1379 [7]

Answer:

3.24

Step-by-step explanation:

You would use the two fonts given to find the scale factor.

So the scale factor would be 10.4976/5.832 = 1.8

So if the scale factor is 1.8 we can use that to find the font size just before that. To do this you would divide the font size by the scale factor.

5.832/1.8 = 3.24

The font size just before 5832 is 3.24.

Hope this helps, if there is an error in my work please correct me.

Find the variable x in the figure if AB ll CD ll EF where c and d are the midpoints of AE and BF.

dangina [55]

CD is called the middle base and is equal to :(AB + EF)/2

CD = <span>(AB + EF)/2

4x = [(x</span>²+10) + (8-x)]/2

8x = x²+10+8-x

8x= x²-x+18
x²-9x+18 = 0

x' = [-b+√(b²-4.a.c)]/2a & x" = [-b-√(b<span>²-4.a.c)]/2a

x'= 6 and x" = 3, So we have2 values of x</span>
