<span>If QRST is a rectangle with QT = 50 and RS = 4x + 8, find x. 
.
QT = RS (opposite sides of a rectangle are equal)

50 = 4x + 8
42 = 4x
10.5 = x</span>

Answer:

10.5 cm

Step-by-step explanation:

The rectangle is organized like this:

Q----------------------R

50                      4x+8

T-----------------------S

So you now know that QT and RS are sides similar to each other, so to finde the value of x you just put them in opposite sides of the equation:

4x+8=50

4x=50-8

4x=42

x=\frac{42}{4}

x=10.5

By doing this you can observe that after evaluating the equation the value of X is 10.5

PLEASE HELP!! I’m very confuse
SVETLANKA909090 [29]

Given:

A(16, 4)

B(34, 40)

Line segment AB partition in the ratio 1 : 5.

To find:

The coordinate of a point that partitions AB.

Solution:

Section formula:

$P(x,y)=\left(\frac{m x_{2}+n x_{1}}{m+n}, \frac{m y_{2}+m y_{1}}{m+n}\right)

Here x_1=16, y_1=4, x_2=34, y_2=40 and m = 1, n = 5

$P(x,y)=\left(\frac{1\times 34+5 \times 16}{1+5}, \frac{1\times 40+5 \times4}{1+5}\right)

$P(x,y)=\left(\frac{ 34+80}{6}, \frac{40+20}{6}\right)

$P(x,y)=\left(\frac{ 114}{6}, \frac{60}{6}\right)

$P(x,y)=(19, 10)

The coordinate of point that partitions the segment AB is (19, 10).

I have two fair spinners. The first has the numbers 1, 2, 3 and 4. The second has the numbers 2, 3, 4 and 5. I spin both spinner
Snezhnost [94]

Step-by-step explanation:

There are 4 * 4 = 16 outcomes from spinning these spinners. You get an odd number by multiplying an odd number by an odd number. Since there are 2 odd numbers on both spinners the successful outcomes are 2 * 2 = 4 so probability is 4 / 16 = 1 / 4.
