Can anybody please help me out with this question I would really appreciate it so much. Please and thank you .

(7x+2)° = (9x–8)°

=>7x –9x = –8–2

=> –2x = –10

=> x = 10/2

=> x = 5

<ADB = (7x+2)°

= 7×5+2

= 37°

<BDC = (9x–8)°

= 9×5–8

= 45 –8

= 37°

<ADC = 37° + 37°

= 74°

olganol [36]

Answer:

a = 16

b = 10

In the equation from the question there's no value that you can determine for c.

Step-by-step explanation:

(4x)(3z+y)+2x(3y+2z)=axz+bxy
12xz+4xy+6xy+4xz
16xz+10xy

Please help me with it is for homework<br><br> I really need help please help me

Solnce55 [7]

Answer:

See explanation

Step-by-step explanation:

Given two expressions:

$2(s+0.5)+2(s+1.5)$

and

$4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4$

a. When $s=0,$

then

$2(s+0.5)+2(s+1.5)=2(0+0.5)+2(0+1.5)=1+3=4$

and

$4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 0+\dfrac{1}{4}\cdot 0\right)+4=4$

b. When $s=12,$

then

$2(s+0.5)+2(s+1.5)=2(12+0.5)+2(12+1.5)=2\cdot 12.5+2\cdot 13.5=25+27=52$

and

$4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 12+\dfrac{1}{4}\cdot 12\right)+4=4(6+3)+4=4\cdot 9+4=36+6=40$

c. Since the value of both expressions at s = 12 are different, the expressions are not equivalent.
