Answer:
the second option : 5 1/3
Step-by-step explanation:
the height (h) in such a right-angled triangle is based on the 2 segments of the baseline : 3 and a
h = 4
the formula is h = sqrt(a×b)
with a and b being the baseline segments.
so,
4 = sqrt(3×a)
16 = 3×a
a = 16/3 = 5 1/3
6z-7z/5=3
(30z-7z)/5=3
30z-7z=15
23z=15
z=15/23
Answer:
(x-9)(x²+9x+81); it'll give a difference of cubes
Step-by-step explanation:
Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.
*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.
The change in temperature for 1 hour would be -5. hope this helps.
Answer:
351 m^2
btw
#1= 448 cm^2
#2=209pi cm^2
#3=351 m^2
and that's all I know hope it really helps we all need it sometimes (;
