Answer:

Step-by-step explanation:

$log_{5}125$ = $log_{5}(5)^{3}$

= $3*log_{5}5$ [since $logm^{n} =n*logm$ ]

= 3*1 [since $log_{a} a=1$ ]

= 3

In the diagram the length of segment TR can be represented by 5x-4.

masya89 [10]

Answer: The correct option is D, i.e., 15 units.

Explanation:

It is given that the length of segment TR can be represented by 5x-4.

From figure it is noticed that the side TR and RV is equal and the length of segment RV is 2x+5. So,

$5x-4=2x+5$

$3x=9$

$x=3$

The value of x is 3, so the length of side RV is,

$2x+5=2(3)+5=11$

In triangle TRS and angle VRS,

TR=VR

$\angle TRS=\angle VRS=90^{\circ}$

RS=RS (common side)

By SAS rule of congruence triangle,

$\triangle TRS\cong\triangle VRS$

Therefore the side TS and VS are congruent sides.

From figure it is noticed that the length of side TS is 6x-3, therefore the length of side VS is also 6x-3.

$VS=6x-3=6(3)-3=15$

Hence, the length of side VS is 15 units and option D is correct.

Solve for y:- y - 18 = 10 y = ? Thank You!

Simora [160]

In this question we can see that there is one unknown variable named “y” and one equation. So it is absolutely possible to find the correct value of the unknown variable “y”. Now let us check the equation that is given and solve it correctly.
y - 18 = 10
y = 10 + 18
= 28
So the value of the unknown variable “y” is 28. I hope this is the answer you were looking for and the procedure is clear to you.

Simplify the expression to a polynomial in standard form: (2x - 1)(-x^2+ 4x + 6)

Rom4ik [11]

Answer:

$(2x - 1)( - {x}^{2} + 4x + 6) \\ = 2x \times - {x}^{2} + 2x \times4x + 2x \times 6 \\ - 1 \times - {x}^{2} - 1 \times 4x - 1 \times 6 \\ = - 2 {x}^{3} + 8 {x}^{2} + 12x + {x}^{2} - 4x - 6 \\ = - 2 {x}^{3} + 9 {x}^{2} - 8x - 6 \\ thank \: you$
