Answer: -72a^3 +108a^2
Collect like terms
(2a)(6a)(2a-8a+9)= (2a)(6a)(-6a+9)=12a^2(-6a+9)
= -72a^3 +108a^2
Answer:
C. 2 units
Step-by-step explanation:
The ratio of side lengths in an isosceles right triangle is ...
1 : 1 : √2
If you don't already have this memorized, you can figure it out using the Pythagorean theorem:
BD² = AD² +AB² = 1 + 1 = 2
BD = √2 . . . . taking the square root
__
We are told that BD = DC, so we know the larger triangle is also an isosceles right triangle. This one has short sides of length √2, so the long side (BC) will have length (√2)×(√2) = 2.
The length of BC is 2 units.
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33
I believe the answer is 10
Answer:
To
view graph
Step-by-step explanation:
To we can say that then we find cut points. For y=0 ⇒
as can be seen in the graph for any value of y greater that 0, x will always take values greater than 1, for values of y less than 0, x will take values less than 1
