Answer:
4) -4
5) -6x-20
Step-by-step explanation:
Add x with x's and numbers with numbers
4) -6x + 9 + 6x -13
-6x+6x+9-13
x's cancel
9-13 = -4
5) 8x - 9 -11 -14x
8x-14x-9-11
-6x-20
hope this helps
<u>Step-by-step explanation:</u>
Here we have , If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then in the form of a paragraph, explain in complete sentences the next steps necessary to completely solve the equation for x. Let's solve this :
2x - 8 = 5x + 3
⇒ 
⇒ 
{ subtract 2x from both side }
⇒ 
⇒ 
⇒ 
{ subtract 3 from both sides }
⇒ 
⇒ 
⇒ 
{ divide 3 from both sides }
⇒
Lets x = width
length = x + 4 (4 meters longer than wide)
A = L * W
192 = x ( x +4)
192 = x^2 + 4x
x^2 + 4x - 192 = 0
(x +16)(x-12) = 0
x - 12 = 0, x = 12
x + 16 = 0, x = -16
so width x = 12
length = 12 + 4 = 16 (4 meters longer than wide)
answer. J
16
Answer:
b because 23.59+ (-16.75) = 6.84
Step-by-step explanation:
the answer is 1 and 4
Start by subtracting, so on #1 subtract 5-8, 8-11, 11-14
then go up to x, -2--1, -1-0, 0-1
