If 8 is the first term, there are 17 terms left to reach the 18th term. So you do -2 x 17 = -34 then do 8 - 34 = -26

(x-p)^2=p<br> -9+12x-6x^2=0
Volgvan

Answer:

Step-by-step explanation:

Hello

(x-p)^2=p (I don’t understand)

-9+12x-6x^2=0

6x^2 - 12x + 9 = 0

3(2x^2 - 4x + 3) = 0

2x^2 - 4x + 3 = 0

\Delta = (-4)^{2} - 4 \times 2 \times 3 = 16 - 24 = -8 < 0 so no solutions

the area of a triangular flower bed in the park has an area of 120 square feet. The base is 4 feet longer than twice the height.
pickupchik [31]

Answer: height = 10 feet

Base = 24 feet

Step-by-step explanation:

Let h represent the height of the triangular flower bed.

Let b represent the base of the triangular flower bed

The formula for determining the area of a triangle is expressed as

Area = 1/2 × base × height

The area of a triangular flower bed in the park has an area of 120 square feet. This means that

1/2 × bh = 120

bh = 120 × 2

bh = 240- - - - - - - - - - - - - - - 1

The base is 4 feet longer than twice the height. This means that

b = 2h + 4

Substituting b = 2h + 4 into equation 1, it becomes

h(2h + 4) = 240

2h² + 4h = 240

2h² + 4h - 240 = 0

Dividing through by 2, it becomes

h² + 2h - 120 = 0

h² + 12h - 10h - 120 = 0

h(h + 12) - 10(h + 12) = 0

h - 10 = 0 or h + 12 = 0

h = 10 or h = - 12

Since the height cannot be negative, then h = 10

Substituting h = 10 into equation 1, it becomes

10b = 240

b = 240/10

y = 24
