<h3><u>Answer:</u></h3>

Below!

<h3><u>Step-by-step explanation:</u></h3>

Given:

y(x + 1) = 51
y = 3

What to prove: x = 16

=> y(x + 1) = 51
=> 3(x + 1) = 51
=> 3x + 3 = 51
=> 3x = 51 - 3
=> 3x = 48
=> x = 16

<h3><u>Conclusion:</u></h3>

We have now proved that x = 16.

Hoped this helped.

Answer:

see explanation

Step-by-step explanation:

y(x + 1) = 51 ← substitute y = 3 into the equation

3(x + 1) = 51 ( divide both sides by 3 )

x + 1 = 17 ( subtract 1 from both sides )

x = 16

HELPPP PLEASE 20 POINTS<br> What is the surface area of this design?

gizmo_the_mogwai [7]

Answer:

197

Step-by-step explanation:

You have 6 sides of this object. So we will calculate six surface areas.

P1=5x5=25 ( on the top)

P2=9x5=45 ( on the bottom)

P3= 5x5= 25 (left side)

P4=6,4x5=32 (rightside)

P5= (9+5)x5/2=70/2=35 ( front trapeze)

P6=P5=35 ( behided trapeze)

P= p1+p2+p3+p4+p5+p6=

25+45+25+32+35+35 =197

Given points A(−2,0), B(−5,3), C(−9,−1), P(7,6), Q(4,0), and R(−4,4), which of the following proves that △ABC~△PQR?

UNO [17]

Based on the SSS similarity theorem, △ABC ~ △PQR because AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5 (option D).

<h3>The SSS Similarity Theorem</h3>

Two triangles having three pairs of sides that are proportional can be proven to be similar by the SSS similarity theorem.

If the triangle ABC and triangle PQR are similar, their corresponding sides will be proportional, meaning that: AB/PQ = BC/QR = CA/RP.

Therefore, using the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , the sides of each triangle is found.

Therefore, it shows that:

AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5

Therefore, based on the SSS similarity theorem, △ABC ~ △PQR because AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5 (option D).
