7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
I think the answer is A I hope you have a wonderful day
The figure on the top left is a triangle with base 11 and height 8, for an area of

Immediately below, we have a rectangle with dimensions 11 and 9, for an area of

Moving to the right, we have a parallelogram with base 9 and heght 11, which again has height

Finally, the rightmost figure is a triangle with base 8 and height 9, for a total of

Sum these areas and you'll get the total area
Answer:
We need 4 topsoils
Step-by-step explanation:
I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:
- S = Height*the base length = 5 * 12 = 60
So the bags of topsoil does Tom need to cover his flower bed is:
=
= 4
We need 4 topsoils
The answer is 678.09 plus 804
