<em><u>Answer is 5, 6, & 7</u></em>
x = smallest number
y = x + 1
z = x + 2
(x)(y) = z^2 - 19
(x)(x+1) = (x + 2)^2 - 19
(x^2 + x) = (x^2 + 4x + 4) - 19
x^2 + x = x^2 + 4x + 4 - 19
x^2 term drops out from both sides
x = 4x + -15
15 = 4x - x
15 = 3x
15/3 = x
x = 5
y = x + 1 = 6
z = x + 2 = 7
Confirm by substituting back in for the variables:
(x)(y) = z^2 - 19
(5)(6) = (7)^2 - 19
30 = 49 - 19
30 = 30 <em><u>[OK]</u></em>
If the gradient is the same but there are different y intersects, the straight lines will never cross but they will be parallel.
the answer is they will never cross
So since the problem says the number 46 is equal to something, you immediately know that your equation will look like this
46 = something
Now, when an unknown number is multiplied by a number, it has the number and a letter right next to it.
example. 23p
So since 23p = 46, your answer is B :) Hope this helped!
<span>The volume of a cone is: Vcone = 1/3 × pi × r^2 × h = 1/3 * 3.14 * (6/2)^2 * 10 = 94.2 in.3. The approximate volume of the funnel is 94.2 cubic inches.</span>
Answer:
A. C= (F-32)
Step-by-step explanation:
F = C + 32
make c the subject of formula
F = C + 32
subtract 32 from both sides
F-32 = C + 32-32
F-32 = C
