Answer:
x^2 - 6x + 9
Step-by-step explanation:
(x-3)^2
(x-3)(x-3)
x^2 -3x -3x + 9
x^2 - 6x + 9
^2 means (x - 3) times itself twice.
(x - 3)(x - 3) multiplying polynomials- Firsts, Outs, Inners, Lasts (FOIL)
Firsts (x* x) Outs (x*-3) Inners (-3 * x) Lasts (-3*-3)
xx -3x -3x +9 Combine like terms.
-3x -3x Adding/subtracting integers- same signs means you add
and keep the sign.
x^2 -6x + 9
Answer:
If its temperature is below 0 °C, then water is frozen.
Step-by-step explanation:
The converse of <em>if A then B</em> is <em>if B then A</em>.
Here, we have ...
A = water is frozen
B = its temperature is below 0 °C
so the converse is ...
If its temperature is below 0 °C, then water is frozen.
Answer:
The center (2,6) and the radius is 8
Step-by-step explanation:
The equation of a circle is (x-h)^2 + (y-k)^2 =r^2
where (h,k) is the center of the circle and r is the radius
We have
(x-2)^2 + (y-6)^2 =64
(x-2)^2 + (y-6)^2 =8^2
The center (2,6) and the radius is 8
Hi!
The equation to find the area of a triangle is...
(a = area
b = base
h = height)
Fill in the values that we already have.Divide both sides by 1/21722 = 82*h
Divide both sides by 82.1722/82 = 82/82*h
21 = h
The answer is B. 21 cmHope this helps! :)
First you subtract 5 from each side. so its 6x+5=29 -5 -5which then you get 6x=24. You then divide 6 from 24 and you get x=4
