Mathematics

We have similar triangles RST ,TSR and TRQ.The triangles are similar to each other .

Similar triangles have sides in proportion.

In similar triangles TQR and TRS:

\frac{TR}{ST} =\frac{TQ}{TR}

Or,

\frac{x}{9} =\frac{16}{x}

Cross multiplying

x^{2}=16(9)

x^{2}=144

Taking root

x=12.

∵ ΔSRQ is a right triangle
and RT⊥SQ
∴ x² = ST * TQ
∴ x² = 9 *16 = 144

∴ x = √144 = 12

What property is this?6x+9/3=2x+3
yan [13]

C. Distributive Property

<h2>Explanation:</h2>

From the complete question, the correct option is C. Distributive Property. We have the following equation:

\frac{6x+9}{3}=2x+3

But we can write this as follows:

\frac{1}{3}(6x+9)=2x+3

So 1/3 multiplies both 6x and 9, that stands for Distributive Property, therefore:

\frac{1}{3}(6x)+\frac{1}{3}(9)=2x+3 \\ \\ 2x+3=2x+3

PLEASE HELP! Which graph has an absolute max at x=2
Dmitry [639]

Answer:

C)

Step-by-step explanation:

The highest point on the graph for c) is in the first quadrant (where x=2 would be).

If you had an equation, you would be able to find critical points on the function by setting the numerator and denominator equal of f'(x)=0 and solve. You'd have to evaluate f(x) at these critical points and end points to figure that out. This is, if you're in calculus and you would ever need assistance otherwise!

What is the value of the expression? ( 5/2 ) ^2 +3/4 ^3
NeX [460]

5/2 ^2 =  6 1/4 = 6.25

3/4^3 =  27/64 = 0.4201875

6 1/4 + 27/64 = 6 43/64  (mixed number)

6.25 +0.421875 = 6.671875 (decimal)


 not sure what format you need, since the question was in fraction form, I think you need to answer using a mixed number though.
