Answer:
13
Step-by-step explanation:
Remark
This only works if B is between AC and F is between AE
Givens
CE = 32
BF = 1/2 CE Properties of midpoints. BF is parallel to and 1/2 of CE
BF = 1/2 * 32
BF = 16
Equation
2x - 10 = 16 Add 10 to both sides
2x - 10 + 10 = 16 + 10 Combine
2x = 26 Divide by 2
2x/2 = 26/2 Do the division
x = 13

Answer:
-8/45
Step-by-step explanation:
- Change 3 3/4 into an improper fraction = 4/15
- To change it into multiplication put the dominator on the top = -2/3 × 4/15
- Then multiply it.
- = -8/45
Answer:
f(x) = 2+√x
Step-by-step explanation:
To shift a function up by k units, add k to the value of the function. Here, you want to shift the square root function up 2 units, so you add 2 to the square root:
f(x) = 2+√x
Answer:
Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.
Step-by-step explanation:
The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².
Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.
So, ab = 72 ........... (1)
Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.
So, the area of rectangle ABCD will be
cm² {from equation (1)}
Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
