Answer:

$AC=25\ units$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

The triangle ABC is an isosceles triangle, because

m∠A=m∠C

therefore

AB=BC

substitute the given values

$5x+5=7x-1$

solve for x

$7x-5x=5+1$

$2x=6$

$x=3$

<em>Find the length of side AC</em>

$AC=6x+7$

substitute the value of x

$AC=6(3)+7$

$AC=25\ units$

What is the eighth term in the sequence x+3, - 2x^2 - 6x, 4x^3 +12x^2

Anastasy [175]

Answer:

$a_8=-128x^8-384x^7$

Step-by-step explanation:

The terms of the sequence are:

$x+3,-2x^2-6x,4x^3+12x^2,...$

We can rewrite the terms in factored form to get;

$x+3,-2x(x+3),4x^2(x+3),...$

We can see that the subsequent terms are obtained by multiplying the previous term by $-2x$ . This is called the common ratio.

Therefore the first term of this geometric sequence is $a_1=x+3$ and the common ratio is $r=-2x$ .

The nth term of a geometric sequence is given by: $a_n=a_1(r^{n-1})$ .

Let us substitute the first term, the common ratio, and $n=8$ to obtain:

$a_8=(x+3)(-2x)^{8-1}$

$a_8=(x+3)(-2x)^{7}$

$a_8=-128x^7(x+3)$

$a_8=-128x^8-384x^7$
