The measures of the sides of a triangle are 2x + 3, 8x – 4, and . write an expression that describes the perimeter of the triangle.

C

Step-by-step explanation:

Perimeter of a triangle is the sum of all the sides.

A triangle has 3 sides, so if we add up all the 3 sides lengths (given as expressions here) of the triangle, we will have the perimeter.

Perimeter =

Now combining like terms we have:

Answer choice C is the correct one.

idk

step-by-step explanation:

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
