Answer: D.
Step-by-step explanation:
52,165 + 49,872 = 102,037
Answer:
We know that an isosceles triangle has 2 of its sides being equal
With R, being the midpoint of PS, we can say that
PR=RS
Noting that, with R as midpoint, we can conclude that RT is a straight line which divides angles TPR and TSR into 2 right angle triangles
Step-by-step explanation:
therefore angle at P is 45°. Angle at S also 45°
Therefore PT = TS
This is because T is 45 degrees as well as P which is also 45 degrees
angle in triangle PTS is 180 degrees
R is 90 degrees, P is 45 degrees and the whole of T is also 45 degrees(which has been split into 2)
Answer:
4x^2 + 11x - 20
Step-by-step explanation:
- area is width X height
- multiply the width (4x - 5) and the height(X + 4)
- I always imagine a multiplication grid for this kind of problem, with X and +4 at the top and 4x and -5 going down, and then combine terms
- you get 4x^2 + 11x - 20
