Evaluate the expression for the given values of the variables -3[w-6 to the power of 2 + x]; w =5,x =6

Put the values of w = 5 and x = 6 to the expression -3[w - 6² + x].

Use PEMDAS:

PParentheses first

EExponents (ie Powers and Square Roots, etc.)

MDMultiplication and Division (left-to-right)

ASAddition and Subtraction (left-to-right)

3[5 - 6² + 6] = 3(5 - 36 + 6) = 3(-31 + 6) = 3(-25) = -75

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
