Answer:
2 real solutions
Step-by-step explanation:
d>0: two real solutions
D=0 one real solution
D<0: two complex (imaginary) solutions
Answer:
Step-by-step explanation:
This is a quadratic equation. All quadratic equations have two solutions. In this case, with d > 0, the two solutions / roots are real, one positive and one negative. To see this, take the square root of both sides of x² = d.

Hello everyone can you answer this for me? What is A in the equation attached? Please and thank you.
Answer:
a = 6
Step-by-step explanation:
Hello!
Solve:
4(3a - 4) = 563a - 4 = 14 (factoring out 4)3a = 18 (adding 4 to both sides)a = 6 (dividing by 3)Another way:
4(3a - 4) = 5612a - 16 = 56 (distributive property)12a = 72 (moving like terms)a = 6 (dividing by 12)Distributive Property of Multiplication:
The process of distributing the outside factor to the terms in the parenthesis.
Example:
[tex]4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16[/tex]
Lauren recorded the price of a gallon of milk at two grocery stores for four weeks.
show your work!!
On average, which grocery store had a better price for milk and by how much?
Discount Mart by $0.08 per gallon
Super Store by $0.08 per gallon
Discount Mart by $0.40 per gallon
Super Store by $0.40 per gallon
Hi,
Discount Mart:
2.99 + 3.19 + 3.55 + 3.05= 12.78
12.78 ÷ 4= 3.195
The average price of milk at Discount Mart is 3.195$
Super Store:
3.19 + 2.79 + 2.99 + 3.49= 12.46
12.46 ÷ 4= 3.115
The average price of milk at Super Store is 3.115$
3.195 - 3.115= 0.08
Therefore we can see that Super Store had a better price on average than Discount Mart by 8 cents.
Your final answer is: "Super Store by $0.08 per gallon"
Hope I could help~ have a good day/night :]

What is the surface area of the Triangular Prism rounded to the nearest tenth?
A)18.5
B) 36.9
C) 43.6
D) 87.2
Answer:
C. 43.6
Step-by-step explanation:
you need to take the area of each shape
lets do the skinny triangles first on the top and bottom of this shape.
so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3
because the formula of a triangle is half the base times height.
so we get 0.5 * 1.26 * 5.3 = 3.339
multiply it by two and we get 6.678
now lets find the area of the huge rectangle on the back/behind of the shape
3.3*5.3 = 17.49
now lets find the area of the two smaller rectangles
3.3 * 3.6 = 11.88
2.3 * 3.3 = 7.59
now lets add
6.678 + 17.49 + 11.88 + 7.59 = 43.638
round it to 43.6

You just multiply the number out of the parentheses by each number inside. If it has a variable, in this case "x" then you just put "x" right after the number.
Example: 2(3x)= 6x
If there is just a negative out of the parentheses then you just change the sign.
Example: -(5x-3)= -5x+3

Two times the cost of a burger and fries is $10. If the fries are $1 how much is the burger?
Answer:
Step-by-step explanation:
b = cost of 1 burgerf = cost of fries$1 = the cost of fries2(b+f) = 10
2b + 2f = 10
2b + 2(1) = 10
2b + 2 = 10
- 2 - 2
2b = 8
/2 /2
b = $4 <== the cost of each burger
Check your answer:
2(b+f) = 10
2(4+1) = 10
8 + 2 = 10
10 = 10
This statement is correct
Hope this helps!
