Answer:
(d) 30 units²
Step-by-step explanation:
The area of the rectangle is the product of the length and width. It is equal to the number of unit squares that fill the rectangle.
__
By counting grid squares or subtracting coordinates, we can see this rectangle is 3 units wide and 10 units high. Its area will be ...
A = WH
A = (3 units)(10 units) = 30 units²
_____
<em>Additional comment</em>
You can also count the three columns of 10 shaded squares, or the 10 rows of 3 shaded squares. Either way, you will count 30 square units covering the rectangle.
Answer = 121°
Parallelograms’ angles are all equal. So the two given are equal.
6x + 13 = 7x - 5
x = 18
Plug x back into one of the original angles
6(18) + 13 = 121
Now we know all the angles are 121°, so that’s the answer
Answer:
12/25
Step-by-step explanation:
2/5 ÷ 5/6
To divide by a fraction, multiply by the reciprocal.
2/5 × 6/5
12/25
Since x can be any value as long as the denominator equals 0 (it doesn't matter if it's positive or negative), we have to figure out when x^2=0, which is when x=0. Therefore, the domain is (-inf, 0) U (0, inf)
