4 weeks change = -20

1 week change = -5

If x is the temperature at the start of the week:

A: (4x-20)/4


B: Change per week = x-5 This means that the temperature goes down by 5 degrees per week, with x being the temperature at the start of the week.

If the length of a rectangle in terms of x is x^2+2x-3 and its width is 2x^2+3x+5, what is the perimeter of this rectangle?
AnnZ [28]

Step-by-step explanation:

perimeter=(L+W)2

L=x^2+2x-3

W=2x^2+3x+5

(x^2+2x-3+2x^2+3x+5)2

(x^2+2x^2+2x+3x-3+5)2

(3x^2+5x+2)2

p=(6x^2+10x+4)units

I will give you 100 points HELp
Naddika [18.5K]

Answer:

CD ≈ 26.0 cm

Step-by-step explanation:

using the sine ratio in right triangle ABD

sin35° = \frac{opposite}{hypotenuse} = \frac{AB}{BD} = \frac{12}{BD} ( multiply both sides by BD )

BD × sin35° = 12 ( divide both sides by sin35° )

BD = \frac{12}{sin35} ≈ 20.92 cm

using the sine rule in Δ BCD

\frac{BD}{sinC} = \frac{CD}{sinB} , that is

\frac{20.92}{sin52} = \frac{CD}{sin102} ( cross- multiply )

CD × sin52° = 20.92 × sin102° ( divide both sides by sin52° )

CD = \frac{20.92sin102}{sin52} ≈ 26.0 cm ( to 3 significant figures )

Please help to solve this<br>Find H.C.F <br>m^3 - 1, m^4 + m^2 + 1, m^2+ m + 1​
Nikitich [7]

Answer:

m^2+m+1

Step-by-step explanation:

  • m^3 - 1= (m-1)(m^2+m+1)
  • m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
  • m^2+ m + 1​

HCF= m^2+m+1 which is the factor of all three polynomials
