Mathematics
1 answer:
Alchen [17]3 years ago
3 0

Answer:

A -8

Step-by-step explanation:

To make the function equal to zero, we need the numerator equal to zero

2x+16 =0

2x+16-16 =0-16

2x=-16

Divide by 2

2x/2 = -16/2

x = -8

What is the value of x?<br> 12 units<br> 15 units<br> 20 units<br> 25 units
Firlakuza [10]

Answer:

The answer is 12 units.

Step-by-step explanation:

Looking at the figure we see that

(1).9^2+x^2=SR^2

(2).16^2+x^2=RQ^2 and

(3).SR^2+RQ^2=(9+16)^2

Now from equations (1) and (2) we have values for SR^2 and RQ^2, so we put those into the equation (3) and get:

9^2+x^2+16^2+x^2=(9+16)^2

\rightarrow 337+2x^2=625

\boxed{\therefore x= 12.}

Therefore the answer is 12 units.

GEOMETRY HELP ASAP I'M FAILING. I did the first half now i cant figure this out!!?
Shalnov [3]
OK, so;
BDE and BED are congruent because the opposite sides are both congruent
To find BDE and BED you must subtract 66 degrees from 180 degrees.
You are then left with 114 as the sum of both the angles you need to find
Since they are congruent, all you need to do is divide by two
114/2=57 degrees for both BDE (a) and BED(b)
Now for angle A and C;
This is easy because they are both congruent to the first two!
So basically, all of question four is "57 degrees"
 Sadly for number 5 i did not understand the question :"(
For 6 tho;
AC is parallel to DE because angle C is congruent to angle BED 
All the others can be ruled out 
For 7;
BD is half the length of AE, so:
 4x+20=2(3x+5)
4x+20=6x+10
20=2x+10
10=2x
x=5
 This means BD is 20 bc
3(5)+5
15+5
20
 And AE is 40 bc
20X2=40
or...
4(5)+20
