Uggh!! help pls last question

The answer is 46.

Step-by-step explanation:

You have to substitute the value of a and c into the expression :

Let a = 10,

Let c = 4,

First, insert the given numbers into the equation. (a = 10 , c = 4)

a + 9c becomes 10 + (9 × 4)

Use PEMDAS  (parenthesis, exponents, multiplication, division, addition, & subtraction) to solve the equation.

First, do the multiplication inside of the parenthesis.

9 × 4 = 36

Now do the addition.

10 + 36 = 46

10 + (9 × 4) = 46

hope this helps :)

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
