Please state the width (part a)
And length (part b)

(a) = 71 cm

(b) = 89 cm

Step-by-step explanation:

(a.)

perimeter of a rectangular field = 324 m

length (l) = 91 m

width (w) = ?

Now,

Perimeter Of Rectangle

= P = 2(l + w)

= 2(91 + w) = 324m

= 182 + 2w = 324m

= 2w = 324 - 182m

= 2w = 142m

= w = 142/2

= w = 71

(b.)

area of rectangular painting = 5696 cm²

width (w) = 64 cm

length (l) = ?

Now,

Area Of Rectangle

A = l × w

= l × 64 = 5696

= l = 5696/64

= l = 89 cm

FOR (a)

= P = 2(l + w)

= P = 2(91 + 71) = 324 cm

FOR (b)

= l × w

A = 89 × 64 = 5696

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
