Answer:
16
Step-by-step explanation:
-2 to the 4th power is expressed as;
= (-2)^-4
= -2 × -2 × -2 × -2
= (-2×-2)×(-2×-2)
= 4×4
= 16
Hence -2 to the 4th power is equal to 16
The origainal answer is 36/5 but the simplest form is 7 1/5
Answer:
See below
Step-by-step explanation:
It is NOT a RIGHT triangle so you <u>cannot use</u> 1/2 b * h
but you can use Heron's Formula
Area = sqrt( s (s-a)(s-b)(s-c) )
s = semi- perimeter = (3+6+7)/2 = 8
Area = sqrt ( 8 ( 8-3)(8-6)(8-7) ) = sqrt ( 80) = 8.9 cm^2
