Write the expression -3x2 + 2y2 + 5xy - 2y + 5x2-3y2 in simplest form. then, answer the following questions using
complete sentences.
a. how many terms are in the simplified expression?
b. how many of the terms in the simplified expression are negative?
writer

2x^2-y^2+5xy-2y

a. There is four terms in the simplified expression.

b. Two terms in the simplified expression are negative.

Step-by-step explanation:

Write the expression like an addition/ subtraction problem.

-3x²+2y²+5xy-2y

+5x²-3y²

This makes it easier to identify what to combine for like terms.

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
