Answer:
+) the area of the original house is:
(x + 8)(x + 12) = x² + 20x + 96.
+) the area of the new addition is:
(x + 6)x = x² + 6x
+) the total area of the house is:
x² + 20x + 96 + x² + 6x = 2x² + 26x + 96
Answer:
a = 3
Step-by-step explanation:

To get the remainder when these polynomials are divided by x - 2, subsitute(x = 2) into both functions.

Since the remainders are the same, p(2) = f(2)
19 - 4a = 4 + a
19 - 4 = a + 4a
15 = 5a
a = 15/5
a = 3
Answer:
16
Step-by-step explanation:
(10-6)^2
4^2=16
Three common tangents is illustrated when two circles touch each other externally at one point and they'll have three tangents.
<h3>How to illustrate the information?</h3>
It should be noted that a common tangent simply means a line the bus tangent to more than one circle.
In this case, three common tangents is illustrated when two circles touch each other externally at one point and they'll have three tangents.
A diagram is attached to illustrate the tangent.
