Step-by-step explanation:
I will give u the steps
add up all of the values
then when you find the total lets say its 100% then total percent of cars would be 32%
The answer is -0.266666667.
Round how you need
#6
x^2 = 1
x = - 1 and x = + 1
#7
a^2 + 1 = 19
a^2 =18
a^2 =√ 9 <span>√ 2
a = + 3</span>√ 2 and a = - 3<span>√ 2</span>
Distributive, if you do 4 times x and 4 times 2 you get 4x+8
