Answer:

The length is 22.5 and the width is 19.5

Step-by-step explanation:

2L + 2W = P

2L + 2W = 84

W + 3 + W + 3 + W + W= 84

4W + 6 = 84

4W = 78

W = 19.5 L = 19.5 + 3 = 22.5

I hope this helps, have a nice day! :D

Algebra work need help please show working

Nastasia [14]

Expand the left side:

(3x + 2) (5x + 1) = 15x² + 10x + 3x + 2 = 15x² + 13x + 2

Then a = 15 and b = 13, so a - b = 2.

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Angle θ = x

Adjacent Leg = 5.8

Hypotenuse = 7.3

Step 2: Solve for x

Substitute in variables [Cosine]: $\displaystyle cosx^\circ = \frac{5.8}{7.3}$
[Fraction] Divide: $\displaystyle cosx^\circ = 0.794521$
[Equality Property] Trig inverse: $\displaystyle x^\circ = cos^{-1}(0.794521)$
Evaluate trig inverse: $\displaystyle x = 37.39^\circ$
Round: $\displaystyle x \approx 37.4^\circ$
