Answer: -2
Step-by-step explanation: When your adding and subtracting positives and negatives, it helps to use a number line to visualise what's going on in the problem.
On a number line zero is in the middle. All numbers to the right of zero are positive and all numbers to the left of zero are negative.
So when your simplifying a problem like 3 + (-5), we start at zero and positive 3 takes us to the right. From there, -5 moves us 5 units back to the left and we end up -2. So 3 + (-5) simplifies to -2.
I have attached a number line along with my work
for this problem below.
Answer:
X=4, x=-6
Step-by-step explanation:
subtract the 24 over. Then factor, what multiplies to negative 24 and adds to 2, which is -4 and 6. Your factors are (x-4)(x+6). set each of those to zero. x=4 and x=-6
To solve this problem you must apply the formula for calculate the area of a rectangle,which is:
A=bh
Where b is the base and h is the height of the rectangle
b=14 ft
h=8 ft
When you substitute these values into the formula, you obtain:
A=(14 ft)(8 ft)
A=112 ft^2
The answer is 112 ft^2
