Answer:
that's not quadratic formula or square method
Step-by-step explanation:
i personally thing the quadratic formula is easier which is
x = -b+-√b^2 -4ac
----------------------------
2a
you just plug in a b and c into the equation which is
x^2 is a which is 1
-6x is b which is -6
1 is c and its just 1
the answer also needs to involve a radical which for example 3√2
Answer:
x = 10 m∠3 = 74
Step-by-step explanation:
(10x + 6) + (7x + 4) = 180 degrees
17x + 10 = 180
17x = 170
x = 10
check answer
(10(10) + 6) + (7(10) + 4) = 180
106 + 74 = 180
180 = 180
true!
angle 5 is vertical angles with 3, so they are congruent
use same equation as 5
7(10) + 4
70 + 4
74 :)
We will see that the equation has only one solution, so the correct option is B.
<h3>
How many solutions an equation has?</h3>
For an equation of the form:
p(x) = C
Where p(x) is an expression that depends on x, and C is a constant.
The solutions are all the values of x that make the equality true.
For our case, we have:
x = -5
Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:
-5 = -5
So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

Answer: 6 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (20/2)^3
v = 4/3 x π x (10)^3 = 4,188.79 in3
Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.
4,188-79 / 693 = 6.04 = 6 fishes
