Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
The surface area will be equal to option B which is 1008 square centimeters.
<h3>What is surface area?</h3>
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The surface area of the prism will be calculated as:-
SA = area of the three rectangular faces + area of the triangular faces
Area of the rectangular faces = ( 15 X 25 ) + ( 25 X 12 ) + ( 25 X 9 )
= 375 + 300 + 225
= 900 square cm
Area of the triangular 
= 
= √2916
= 64
Total area of the rectangular face = 2 x 54 = 108
So the total SA area of the prism will be = 900 + 108= 1008 square cm.
Therefore surface area will be equal to option B which is 1008 square centimeters.

Answer:
I think the answer is that Best Market sells strawberries at a higher unit price, and that you would have to pay $5.40 more at that store than the other.
Step-by-step explanation:
If we take a look at the graph, we can see that 1 pound of strawberries is worth 2$. That makes the unit price, or the price of per one unit of the item, 2$ for Fine Foods.
In thd directions, they gave us the equation y = 2.9x for strawberries at Best Market. To find the unit price for Best Market, we would have to substitute x for 1 since x represent pounds, and we're trying to find how much 1 pound costs to find the unit price. It would look like this:
y = 2.9 (1)
y = 2.9
So, the unit price at Best Market would be 2.90$.
Comparing the unit prices, 2.90$ is bigger than &2. So, Best Market sells strawberries at a higher unit price. To find out how much 6 pounds of strawberries at Best Market is, all we have to do is substitute x for 6 in y = 2.9x like so:
y = 2.9 (6)
y = 17.40
So, the price for 6 pounds of strawberries is 17.40$ at Best Market. If we refer to the graph for the cost of 6 pounds at Fine Foods, then we know that 6 pounds of strawberries is 12$. 17.40 - 12 = 5.4. So, you would have to pay $5.40 more for 6 pounds at Best Market than Fine Foods.
