<h3>Answer: Choice B</h3>

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

Explanation:

Using your calculator, you should find that

  • sqrt(125) = 11.1803 approximately
  • sqrt(196) = 14 exactly
  • sqrt(207) = 14.387 approximately
  • sqrt(220) = 14.832 approximately

Each approximate result has its decimal digits go on forever without any pattern. So we cannot write those values as a fraction of two integers. The decimal expansion must have some kind of pattern that repeats forever, so we could consider it rational.

Only choice B results in a whole number. The value 14 is the same as 14/1, showing it can be written as a fraction of two integers. Therefore choice B is rational.

PLZ HELP!!!!!! What is 1-34 divided by (3x8-7) - 2x3
serious [3.7K]
You do the brackets first so 3x8 = 24 - 7 = 17

You then do divide so 34/17 = 2

You then do the multiplication so 2x3= 6

Then you have 1-2-6 = - 7

The order you do it in is BIDMAS
B = brackets
I = indices
D = division
M = multiplication
A = addition
S = subtraction

So the answer is - 7

The coordinates of the image of line segment RT are R’(-2, -4) and T’(4, 4). The image was produced by a dilation with a scale f
lukranit [14]

Answer:

R(-4,-8) and T(-8,8)

Step-by-step explanation:

  • Dilation multiplies or divides. Since it is .5 dilation, the pre-image has greater points.
  • This multiplying each end point by 2 gives us our pre-image values.

ILL GIVE BRAINIEST find the solption for each system of equations using substitution. check ur solution in both original equatio
Verizon [17]

Answer:

X= 2

y = 2

Step-by-step explanation:

y=-2x+6............... equation 1

y=3x-4................... equation 2

from equation 2

y=3x-4

substitute y=3x-4 in equation 1

3x-4=-2x+6

collect like terms

3x+2x=6+4

5x=10

divide both sides by 5

X=2

substitute X=2 in equation 1

y=-2x+6

y=-2(2)+6

y=-4+6

y=2

hope it helps
