Answer:
The integer would -3.
Step-by-step explanation:
Think of it this way:
The elevator goes +7 (Positive = Up) and then -4 (Negative = Down). What is 7-4? That's easy it's just 3. But since the floor level goes down, <u>it would be negative.</u> So you just make it -3.
Check your work:
If we went up from the 4th floor by three, we would get up to the 7th floor.

Answer:
Let the first angle be x .
According to question,
second angle = x+40
then,
x+x+40 = 90
2x = 90 - 40
2x = 50
x = 25
first angle =x=25
second angle=x+40= 65
Step-by-step explanation:
Answer:
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

Answer:
b.
Step-by-step explanation:
Quadratic equations are suppose to be written as:
so the new quadratic equation for this problem will be:
Now rearrange the terms:
Then use the Quadratic Formula to Solve for the Quadratic Equation
Quadratic Formula =
Note: Ignore the A in the quadratic formula
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.
a = 3
b = -7
c = -1
