ASHA 777 [7]2 years ago
6 0

Answer:

2 and 4.

Step-by-step explanation:

  • 2 is not a square because a trapezoid does have 4 sides, but the sides are not parallel, or congruent. ↓
  • 4 is not a square because similar to the trapezoid, it does have 4 sides, but is not parallel nor congruent. ↓
  • Although some people consider a rectangle a square, it is a square and also is not because it has 2 pairs of parallel sides, instead of all 4 sides being parallel.

Hope it helps!

Answer:

SSS

∆PQR = 43

Step-by-step explanation:

The postulate to solve ∆PQR ≅ ∆STU is SSS. Both of the triangles have all three sides given, which means it can be solved for congruence.

9 + 6y + 5 + 14 = 9 + 8y +14

28 + 6y = 9 + 8y + 14

28 + 6y = 8y + 23

      -6y    -6y

--------------------------

  28 = 2y + 23

 -23           -23

---------------------

      5 = 2y

     ----   ----

      2      2  

  2.5  =   y

9 + 14 + 6(2.5) + 5

23 + 15 + 5

 23 + 20

     43

∆PQR = 43

Help gai I need help its a math
dem82 [27]

Answer:

B

Step-by-step explanation:

Rewriting in slope-intercept form.

x - 2y = 0

Add -x on both sides.

- 2y = 0 - x

Divide both sides by -2.

y = 0/-2 - x/-2

y = 0 - - 1/2x

y = 0 + 1/2x

y = 1/2x + 0

The slope is 1/2, the y-intercept is at (0, 0).
