Answer: 11y^2 - 26y
Answer: x = 1
Step-by-step explanation:
isolate the variable by dividing both sides by factors that don't contain the variable.
9x^2 + 9x + 1
36b^2 − 24b + 8
16x^2 + 24x + 9
4a^2 − 10a + 25
Answer:
16x^2 + 24x + 9
Step-by-step explanation:
perfect square trinomial is of the form
a^2 + 2 * a * b + b^2
9x^2 + 9x + 1 = (3x)^2 + 3*3x*1 + 1^2 not a perfect square trinomial
36b^2 − 24b + 8 = ( 6b)^2 -2 * 6b *2 + ( 2 sqrt(2)) ^2 not a perfect square trinomial
16x^2 + 24x + 9 = ( 4x) ^2 + 2 * ( 4x) * 3 + 3^2 = perfect square trinomial
4a^2 − 10a + 25 = ( 2a) ^2 - 1 * 2a *5 + 5^2 not a perfect square trinomial
Answer:
The third answer listed:
Step-by-step explanation:
The trinomial:
can be factored out as follows:
which as can be seen,is the perfect square of a binomial, so this trinomial is what is called a perfect square trinomial.
Answer:
=3^x +12x -4
Step-by-step explanation:
f(x)=3^x+10x
g(x)= 2x-4,
(f+g)(x) = 3^x+10x+ 2x-4,
Combine like terms
=3^x +12x -4
Answer:
d = 8
Step-by-step explanation:
Given
8 + 4d = 5d ( subtract 4d from both sides )
8 = d
Answer:
d=8
Step-by-step explanation:
8+4d=5d
1. subtract 8 from both sides > 8+4d-8=5d-8
2. simplify > 4d=5d-8
3. subtract 5d from both sides > 4d-5d=5d-8-5d
4. simplify again > -d = -8
5. divide both sides by -1 > -d/-1 = -8/-1
6. simplify again > d=8
