Hello :
<span>h(x) = 6x² − 60x + 147= (x² -2(30)x+30²)-30²+147
</span>h(x) = (x-30)²-753 .....(vertex form)
<span>the axis of symmetry is the line of equation : x=30</span>
Answer:
Step-by-step explanation:
28800 = 2 * 2 * 2 * 2 * 2 * 3 * 3 * 10 * 10
You need one 2
You need one 3
You need one 10
28800 * 2 * 3 * 10 = 2 * 2 * 2 * 2 * 2 * 2 * 3 * 3 * 3 * 10 * 10 * 10
(2*6 * 3* 3^3 * 10^3) ^(1/3)
2*2 * 3 * 10 is the cube root
120
Step-by-step explanation:
-4x – 2y= -18
Add 2y to both sides
-4x- 2y+ 2y = -18 + 2y
Simplify
-4x = -18 + 2y
Divide both sides by -4
-4x/-4= -18/-4+ 2y/-4
simplify
x= - -9+y/2
27km* 10^6= 2,700,000cm
Or
1km is 1,000,000 cm, so that means 27 km is 2,700,000 cm
Hope this helps :)
Answer:
20 - 17
Step-by-step explanation:
