When we first learn arithmetic, we focus on working with whole numbers. Then, we extend our understanding to fractions and negat

ive numbers.
In algebra, we transfer these same skills to expressions involving variables. What elementary skills have you used so far in this course, and how have you extended them?

vodka [1.7K]2 years ago

Answer:

I don't think I can remember every skill I was taught through the years but in Kindergarten we used Number Sense so we could understand the meaning of more and less also there's estimation and  PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.

hope that helps

There are 2 way to solve this.

one using Pythagoras theorem and 2nd using trigonometry

so lets solve it by both

using Pythagoras theorem we know

base^2 + perpendicular^2 = hypotanes^2

6^2 + x^2 = 12^2

36 + x^2 = 144

x^2 = 144- 36 = 108

x = √(108) = √( 2×2×3×3×3)

= (2×3) √ (3) = 6 √3

so answer is option 2

bow lets use trigonometry

we know
sin theta = perpendicular / hypotanes
sin 60 = x /12
x = 12 × sin 60
we kNow sin 60 = √3/ 2
so
x = 12×√3 /2 = 6√3

Which number line shows the solution for
Brums [2.3K]

Answer:

It's the last choice.

Step-by-step explanation:

| n | ≤ 2  represents the distance between n and 0 that is less than or equal to 2.  The dots on the 2 and -2 are black because the equal sign is part of the inequality.

Note the vertical lines about the n mean the absolute value of n - the positive distance between  n and 0, which has a maximum of 2 either side of the 0.

Which choice shows the coordinates of B’ if the trapezoid is reflected across the x-axis?
Strike441 [17]
For this case we have that the original point is given by:
 B = (7, 2)
 As the point is reflected through the x axis, then we have the following transformation:
 (x, y) --------------> (x, -y) -------------> (x ', y')
 Applying the transformation to the original ordered pair we have:
 (7, 2) --------------> (7, - (2)) -------------> (7, -2)
 Answer:
 
Point B 'is given by:
 
B '= (7, -2)
