 a² + 2ab + b² = (a+b) * (a + b)   <span>pattern condensed multiplication</span>

 x²      +        10x      +  25
 a²      +        2ab      +  b²    

(1x)²  +      2*1x*5    + (5)²   =     (a+b)*(a+b)
a=x         2ab= 10x      b=5  =     (x+5)*(x+5)

Answer : (x+5)*(x+5)

The recursive definition for the geometric sequence is given as follows:

a_n = 3a_{n-1}, a_1 = 1.7

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

a_n = a_1q^{n-1}

In which a_1 is the first term.

The recursive definition of a geometric sequence is given by:

a_n = qa_{n-1}

In this problem, we have that the first term and the common ratio are given, respectively, by:

a_1 = 1.7, q = \frac{15.3}{5.1} = \frac{5.1}{1.7} = 3.

Hence the recursive definition is given by:

a_n = 3a_{n-1}, a_1 = 1.7

Describe in words how you would solve<br><br>the linear system y = 3x + 1 and y = - 2x + 3.
disa [49]

Answer:

Below.

Step-by-step explanation:

As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.

W then solve this equation for x then substitute this value of x  in the first equation ( y = 3x + 1) to find the value of y.

sharon is building a rectangular patio the patio will be 18 bricks wide and 29 bricks long.she has 500 bricks. does she have eno
Goryan [66]
Since this is area you'll simply just do 18 x 29 which equals 522 and compare it to the amount of bricks she currently has. In this case, no, Sharon does not have enough bricks as she is 22 bricks short.

aniked [119]

Answer:

I think it's just E.

Step-by-step explanation:

When you name triangles, you would often put a Δ and then the letters of the 3 angles. The only answer that fits that criteria is E.
