Answer:
17.2
Step-by-step explanation:
(14)2+(10)2=
c2\,\,c^{2}c2
Use the Pythagorean Theorem.
196+100=196+100=196+100=
Simplify.
296=296=296=
±296=\pm\sqrt{296}=±296
=
c2\,\,\sqrt{c^{2}}c2
Square root both sides.
17.204650...=17.204650...=17.204650...=
c\,\,cc
Simplify. Ignore negative root, as length must be positive.
17.2≈17.2\approx17.2≈
Round to the nearest tenth.
15.6=c
(12)^2+(10)^2=c^2
144+100=c^2
244=c^2
square root of both sides=244= square root c^2
15.620499=c
3x+5 =x+2
3x-x=2-5
2x= –3
x=-3/2
4y+7=y+3
4y–y =3-7
3y=–4
y= —4/3
It went down 5.5°C a minute.
You have to look for the difference of 100 and 78, which is 22.
Divide the difference with the minutes (4), equalling 5.5.
0 is greater than -0
Hope this helps
