Answer:
32
Step-by-step explanation:
(a+b)²=a²+2ab+b²=(a²+b²)+2ab=16+2*8=32
Answer:
A. 44+4x
B. The error is that Ben forgot to distribute his terms by multiplying 7 by 15 so instead of 30x+7 he should have gotten 30x+105
C. (44+4x)-(12x+20) to solve for difference in perimeter
Step-by-step explanation:
One line of symmetry an isosceles trapezoid has
Answer:
<u>Secant</u>: a straight line that intersects a circle at two points.
<u>Intersecting Secants Theorem</u>
If two secant segments are drawn to the circle from one exterior point, the product of the measures of one secant segment and its external part is equal to the product of the measures of the other secant segment and its external part.
From inspection of the given diagram:
- M = Exterior point
- MK = secant segment and ML is its external part
- MS = secant segment and MN is its external part
Therefore:
⇒ ML · MK = MN · MS
Given:
- MK = (x + 15) + 6 = x + 21
- ML = 6
- MS = 7 + 11 = 18
- MN = 7
Substituting the given values into the formula and solving for x:
⇒ ML · MK = MN · MS
⇒ 6(x + 21) = 7 · 18
⇒ 6x + 126 = 126
⇒ 6x = 0
⇒ x = 0
Substituting the found value of x into the expression for KL:
⇒ KL = x + 15
⇒ KL = 0 + 15
⇒ KL = 15
The inverse is:

Given function
<u>Step 1: Replacing f(x) with y</u>
<u>Step 2: Replacing x with y and y with x</u>
<u>Step 3: Solving the equation for y</u>
<u>Step 4: Replacing y with f-1(x)</u>
So, the inverse is:
