Parallelogram P Q S R is shown. The length of P Q is (2 x + 5) centimeters and the length of R S is (4 x + 1) centimeters. In parallelogram PQSR, what is PQ? 2 cm 5 cm 6 cm 9 cm

9cm

Step-by-step explanation:

Opposite sides of a parallelogram are parallel (congruent). This shows that

PQ = RS

2x+5 = 4x+1

2x-4x = 1-5

-2x = -4

x = -4/-2

x = 2

Get PQ

PQ = 2x+5

PQ = 2(2)+5

PQ = 4+5

PQ = 9cm

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

its line 2 i just added the rest or else it wouldn't let me answer
