I will mark Brainliest What is the value of X one number is 78 https://static.k12.com/nextgen_media/assets/8124481-NG_IMB_SemB_ST_Pt1_DP157_261_005_01.png

Answers

Answer 1
Answer: You have two crossed lines. They form a total of 4 angles. The x and 78 are straight across from each other. When that happens, the two angles are labeled as vertically opposite angles. 

Vertically opposite angles are always equal

x = 78 <<<<<<<< answer
Answer 2
Answer: The right answer should be 78

Can someone help me with math?Come up with and describe two scenarios: one that models a direct variation situation and one that models an inverse variation situation. Do not state explicitly which scenario is which, but provide at least four data pairs for each situation. Your classmates will have to determine which of the scenarios is a direct variation and which is an inverse variation, and the value of k for each.

What is the factored form of 2x3 + 4x2 – x?a) 2x ( x^2 + 2x + 1)
b) x (2x^2 + 4x + 1)
c) 2x (x^2 + 2x - 1)
d) x (2x^2 + 4x -1)

Answers

To solve this question, we need to write this equation in simplified form.
So, Taking the GCF from 2x³ + 4x² - x,  
x is divisible by all of them so our new equation will be,

x ( 2x² + 4x - 1)
Correct option is D.

Hope this helped you.. :)

Factor completely 9ab + 12ax − 6b − 8x.Prime

(3b − 4x)(3a − 2)

(3b + 4x)(3a − 2)

(3b + 4x)(3a + 2)

Answers

Okay so you split 9ab + 12ax - 6b - 8x 
             into two 2-term polynomials 
              + 12ax + 9ab   and     - 6b - 8x
             doesn't look that good to me so lest try other one : 
             9ab + 12ax   and     - 6b - 8x
              looks good for now 

            Pull out from each binomial separately
             9ab + 12ax   =   3a • (3b + 4x)
              - 6b - 8x   =    - 2 • (3b + 4x)

           Add up to arrive at the desired factorization so now you have
             (3a - 2) • (3b + 4x)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hope that Helped!

Answer:

C: (3b + 4x)(3a − 2) is the correct answer.

Step-by-step explanation:

the area of a rectangular field is x^2-x-72 m^2. The length of the field is x+8 cm. What is the width of the field meters.

Answers

Hello,


A(x)=x²-x-72 (m²)
L=(x+8) (cm)= (x+8)/100 (m)

We suppose here x≠-8
(in reality x²-x-72>0 ==>x<-8 or x>9
but x+8>0 ==> x>-8
 then
only x>9 are solutions)

W=A(x)/ ((x+8)/100 )=100*(x²-x-72)/(x+8)= 100*(x-9)(x+8)/(x+8)=100*(x-9)
