Answer:
2nd option
Step-by-step explanation:
The shaded area = outside area - inner area
= x² - (x - 6)² ← expand using FOIL
= x² - (x² - 12x + 36) ← distribute parenthesis by - 1
= x² - x² + 12x - 36 ← collect like terms
= 12x - 36
Answer:
x = 6
Step-by-step explanation:
2x + 7 = 19
-7 -7
2x = 12
*divide both sides by 2*
x = 6
I think the answer is 35 km per hour because they are travelling in steady rate and the graph chart is showing the times and all
6x-4y=-14
2(-3x-3y=12)
6x-4y=-14
-6x-6y=24
-10y=10
Divide both sides by 10
-1y=1 divide by -1
y=-1
6x-4(-1)=-14
6x+4=-14
-4 -4
6x=-18
Divide both sides by 6
x=-3
To solve for x in the given equation;

We start by collecting like terms, as follows;

When a number crosses the sign of equality, the sign in front of it switches. Positive numbers becomes negative, and vice versa.
We would now have;
