aivan3 [116]

Step-by-step explanation:

ok so for number 1 you first have to group the like terms therefore you will now have:

and now you calculate:

9r-4r=5r

8-6=2

so that means 5r-2 is simplied version for no.1

for number you 2 you first multiply why is inside the brackets by what is in the outside:

Do all triangles have right angles why or why not
Papessa [141]
Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.

For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).

Some triangles may have right angles (90</span><span>°), but not all do.

What is the area of shaded section of the circle?​
bazaltina [42]

Answer:

≈ 565.5 units²

Step-by-step explanation:

The area (A) of the shaded sector = area of circle × fraction of circle

A = πr² × \frac{162}{360} ← r is the radius

   = π × 20² × \frac{162}{360}

   = 400π × 0.45 ≈ 565.5 units²
