Mathematics
1 answer:
Sati [7]3 years ago
3 0

Answer:

The value of k is 240

Step-by-step explanation:

\frac{1}{3}k + 80 = \frac{1}{2}k + 120

Or, 120 - 80 =  \frac{k}{2} - \frac{k}{3}

Or, 40 = \frac{k}{6}

So. k = 40 × 6  = 240

Hence The value of k is 240   Answer

What substitution should be used to rewrite 6(x + 5)2 + 5(x + 5) – 4 = 0 as a quadratic equation? u = (x + 5) u = (x – 5) u = (x
Pachacha [2.7K]
6(x+5)² + 5(x+5)-4 = 0

(x+5)(x+5) = x(x+5)+5(x+5) = x² + 5x + 5x + 25 = x² + 10x + 25

6(x²+10x+25) + 5(x+5) - 4 = 0
6x² + 60x + 150 + 5x + 25 - 4 = 0
6x² + 60x + 5x + 150 + 25 - 4 = 0
6x² + 65x + 171 = 0

Mr Floyd is laying grass squares in his backyard. He will cover the entire yard except for the vegetable garden. How many square
Alenkasestr [34]

Here we can first find the area of yard and then subtract the area of vegetable garden to get the required area.

The formula to find area is given by:

A = l* w

Now we find area of yard:

length is 25 ft and width is 15 ft.

A = 25 * 15

Area of yard = 375 ft²

Area of vegetable garden:

length = 8ft and width =8ft

So the vegetable garden is a square.

Area = 8*8

Area of vegetable garden =64 ft²

Area of backyard to be laid with grass = Area of yard-Area of vegetable garden

Area required = 375 -64 = 311 ft²

Answer : The area of backyard in which grass is to be laid is 311 square feet.
