Find QD if QB=21 and PC=11

alexdok [17]

Answer:

The answer to your question is: 21

Step-by-step explanation:

Data

AB = BC = CD

BQ = 21

QD = ?

PC = 11

Process

Here there are 2 triangles

ΔQCB and ΔQCD

These triangles share one side QC

And one side measures the same BC = CD

And the ∠ BCQ = ∠ DCQ

Then these triangles are congruents SAS

if QB = 21 then QD = 21

:( <br> A=?<br> B=?<br> please help me

Helen [10]

a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

$2(l + b)$

So therefore

$2(8x + 3 + 5) = a$

$= > 16x+ 6 + 10 = a$

$= > 16x + 16 = a$

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

$(8x + 3) \times 5$

$= 40x + 15$

Answer = b) that is area is 40x + 15

Question 37 (1 point)

o-na [289]

Answer:

The probability is:

$P =\frac{1}{16}$

Step-by-step explanation:

Keep in mind that the probability of getting a head is always the same for each

$p = 0.5$

Therefore the probability of not having a head is:

$q = 1-p = 0.5\\q = 0.5$

So if we throw the coin 4 times the probability P of not getting any head is:

$P = q * q * q * q\\\\P = q ^ 4\\\\P = 0.5 ^ 4\\\\$

$P =\frac{1}{16}$

How many points are shared by two perpendicular lines? but two parallel lines?

ratelena [41]

Two perpendicular lines intersect once, to form a right angle. Therefore, on point is shared by two perpendicular lines. since parallel lines never touch, there are NO points shared between the two lines.
