7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the gard

galben [10]

Answer: $15r^2-21r+5$

Step-by-step explanation:

Given: Perimeter of triangular garden = $25r^2 - 9r + 14$

The sum of two sides of the garden = $10r^2 + 12r + 9$

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

$=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5$

The expression represent the third side = $15r^2-21r+5$ .

Find the stationary points on the curve y = (3x – 1)(x - 2)^4.

Stels [109]

Step-by-step explanation:

by using y=uv derivative formula and stationary mean y' = 0

y' = 3(x–2)⁴ + 3(3x–1)(x–2)³ = 0

cancel 3 and factorize

(x–2+3x–1)(x–2)³ = 0

x = ¾ or x = 2

we got point $\left(\frac{3}{4},\frac{5^5}{4^5}\right)$ and (2,0)
