All real numbers are correct! Hope that helps.

Answer:

a can be anything. There are infinite solutions.

Step-by-step explanation:

4(a+2)=8+4a

Expand:

4a+4\times\:2=8+4a

4a+8=8+4a

Subtract 8 from both sides:

4a+8-8=8+4a-8

4a=4a

Subtract 4a from both sides:

4a-4a=4a-4a

0=0

Since both sides are equal, a has infinite solutions as no matter what value it is, it will not affect the end result of 0=0 which is true.

<h3>Answer:  161 degrees</h3>

=========================================================

Explanation:

Line AE is a tangent while line AU is a secant. The angle formed by the secant and tangent lines connects with the arcs through this formula

secant tangent angle = (larger arc - smaller arc)/2

More specifically, we can say:

angle EAI = (arc EU - arc IE)/2

42 = ( (7m+5) - (3m-1) )/2

42*2 = (7m+5) - (3m-1)

84 = 7m+5 - 3m+1

84 = 4m+6

4m+6 = 84

4m = 84-6

4m = 78

m = 78/4

m = 39/2

m = 19.5

Use this value of m to compute each arc

  • arc IE = 3m-1 = 3*19.5-1 = 57.5 degrees
  • arc EU = 7m+5 = 7*19.5+5 = 141.5 degrees

Let's say arc IU is some unknown number x. It must add to the other two arc measures to form 360 degrees, which is a full circle.

(arc IU) + (arc IE) + (arc EU) = 360

x + 57.5 + 141.5 = 360

x + 199 = 360

x = 360-199

x = 161

The measure of minor arc IU is 161 degrees

Can someone please explain what solving in scientific notation is?
nikitadnepr [17]

Step-by-step explanation:

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.

For example, instead of writing 0.0000000056, we write 5.6 x, 10^-9
