a over b if im not mistaken
Step-by-step explanation:
Answer:
A. −19z − 77
Step-by-step explanation:
−9(z + 3) − 5(2z + 10)
The first step is to distribute
-9*z -9*3 -5*2z -5*10
-9z-27 -10z-50
-19z -77
The diagram is not given. I will however write out each polynomial, so that you can select whichever corresponds to your question.
Step-by-step explanation:
(2x + 8)(4x + 8)
= 8x² + 16x + 24x + 64
= 8x² + 40x + 64
= 8(x² + 5x + 8)
(x + 2)(x+4)
= x² + 4x + 2x + 8
= x² + 6x + 8
(x + 1)(x+8)
= x² + 8x + x + 8
= x² + 9x + 8
* (*+ 4x)(2x + 3) NOT CLEAR
The common denominator is 12, the lowest number that has both six and four as factors.
Answer:

Step-by-step explanation:
we have
----> equation A
-----> equation B
----> equation C
adds equation A and equation C

-----> equation D
adds equation B and equation C

-----> equation E
we have the system
-----> equation D
-----> equation E
Multiply equation E by -1.5 both sides

-----> equation F
adds equation D and equation F

<em>Find the value of z</em>
substitute the value of y in equation E (or substitute in equation D)




<em>Find the value of x</em>
substitute the value of y and z in equation A (or equation B or C)




therefore
The solution of the system of equations is
