Answer:
35
Step-by-step explanation:
-5{3-2[1-4(3-2^2)]}
we work inside out
using PEMDAS
parenthesis, exponents, multiply and divide, add and subtract
the very most inside
(3-2^2)
do the exponents
3 - 4 = -1
replace where it was in the original equation
-5{3-2[1-4(-1)]}
take the next set of parenthesis (bracket are the same as parenthesis)
[1-4(-1)]
multiply
4*-1 = -4
1--4 = 1+4 = 5
replace where it was in the original equation
-5{3-2[5]}
next set of parenthesis
{3-2[5]}
3 - 10 = -7
replace where it was in the original equation
-5 {-7}

The Angles that cosine are Angles A,C,Z,and W
What ever number A is, it is going to be less than whatever number B is.
The total distance travelled is 1075.91 km.
<h3>What is average speed?</h3>
The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
45 * (x +12)= 50* 1/5 + 1/2 *x
45x + 540= 10+ 0.5 x
44.5 x = 530
x= 11.91 (neglect the negative sign cause time can't be negative)
So, distance= 45* 23.91 = 1075.91 Km
