l (length)=3x

P (perimeter)= 8x+6 = 2 x length + 2 x width

8x+6 = 2 (3x) + 2 x width

8x+6 = 6x + 2 x width

2 x width = 8x+6 - 6x

2 x width = 2x+6

width = 1/2(2x+6) = x + 3

Hope it helps

What is the value of x in the model below? Enter your answer in the box.

sp2606 [1]

It looks like the scale is balanced so that means you can set one side equal to the other which leaves you with the equation x+(-10)=-16

To get x by itself add x to each side to get x=-6

X=-6 is your answer

Answer:

Part A) Option A. QR= 3 cm

Part B) Option B. SV=6.5 cm

Step-by-step explanation:

step 1

Find the length of segment QR

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem Triangle QRW and Triangle QSV are similar by AA Similarity Theorem

$\frac{QR}{QS}=\frac{QW}{QV}$

we have

$QS=9\ cm$ ---> because S is the midpoint QT (QS=TS)

$QW=2\ cm$ --->because V is the midpoint QU (QW+WV=VU)

$QV=6\ cm$ --->because V is the midpoint QU (QV=VU)

substitute the given values

$\frac{QR}{9}=\frac{2}{6}$

solve for QR

$QR=9(2)/6=3\ cm$

step 2

Find the length side SV

we know that

The Mid-segment Theorem states that the mid-segment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this mid-segment is half the length of the third side

In this problem

S is the mid-point side QT and V is the mid-point side QU

therefore

SV is parallel to TU

and

$SV=(1/2)TU$

$SV=(1/2)13=6.5\ cm$

Question of the day.

matrenka [14]

$\lambda = _0^{200}\sum (i)^f = 1+50(i-1-i+1) = 1 + 0i$
From this we know that $\lambda$ lies on the x-axis.
If z = 0, then k = $\lambda$ and point lies on curve L.

I believe the answer is C. It definitely not A or B.
