In this question, the triangle has 2 same <span>side:SR=ST</span>. That mean the angle of R will be same as T.
S= 7x-54
If STU=8x then T=R= 180-8x

If you add all 3 angle of triangle it will be 180. Then,
R+S+T= 180
7x-54 + (180-8x)+(180-8x)= 180
7x +360-16x= 180+54
-9x= 234-360
x= 14

Can someone please answer step by step?

alukav5142 [94]

Answer:

George is correct

Step-by-step explanation:

if the jacket is in sales for 20% off, Jane's coupon would give her a discount of 10% on top of the already discounted 20%.

Jane is incorrect because, if she added the 2 discount together, she gets a total of 30%, but that is a 30% discount of the original price of $75 which isn't correct. what we want to do is find how much the jacket cost after 20% discount THEN use the coupon to get a further 10% discount on the sales price of the jacket. and for this reason, George is correct.

hope this helped

What is the multiplicity of each of the roots of the graph of

pantera1 [17]

Answer:

The correct option is;

C. -3, multiplicity 2; -1, multiplicity 1; 1, multiplicity 1

Please find attached the required function graph

Step-by-step explanation:

To solve the equation f(x) = 2·x⁴ + 12·x³ + 16·x² -12·x - 18, by graphing the function, we have;

x ${}$ F(x)

-4 ${}$ 30

-3 ${}$ 0

-2 ${}$ 6

-1 ${}$ 0

0 ${}$ -18

1 ${}$ 0

2 ${}$ 150

The shape of a graph with multiplicity of 2

Given that the graph bounces of the horizontal axis at the y-intercept at point x = -3, the factor (x - 3) must be a quadratic of the form (x - 3)², thereby having a multiplicity of 2 in the solution which are;

x = 1, -1, and, giving

(x - 1)·(x + 1)·(x - 3)² = 0

Therefore, the correct option is -3, multiplicity 2; -1, multiplicity 1; 1 multiplicity 1.
