Step-by-step explanation:
You "had" 2 dogs, so you have no pets in total.
40 x 8 is 320, and there’s 31,536,000 seconds in a year so multiply both of those :)
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}

Answer:
Q1. Regular (A)
Q2. 105° (C)
Q3. x=45°
Step-by-step explanation:
Q1. A regular polygon is a polygon with all sides and angles equal.
Q2. The sum of the measure of exterior angles of a polygon is always 360°. Therefore, 360°-255°=105°
Q3. 148°+112°+(2x+10)°+(2x)°+90°= Sum of angles in a pentagon.
<u><em>Note</em></u>: The square at the fifth angle shows that its a right angle which is 90°. Also all the angles are equal to the sum of angles in a pentagon 'cause the polygon has 5 sides ( a pentagon).
Sum of interior angles of a polygon is: (n-2)180°. Where "n" is the number of sides of the polygon.
Therefore the sum of interior angles is (5-2)180°=540°
solving the equation you have;
360°+4x=540°
4x=540°-360°
4x=180°
x=180°/4
x=45°
therefore x=45°
I do not know the first one, but the second one is variable and the last one is a constant
