Answer: x = 1 and x = -7
Explanation:
x^2 + 6x - 7 = 0
x^2 + 6x + 3^2 = 7 + 3^2
(x + 3)^2 = 16
x + 3 = +-4 (square both sides)
x + 3 = 4
x = 1
x + 3 = -4
x = -7
Answer:
THE VALUE OF x = 20 ;
Step-by-step explanation:
Since the quadrilateral PQRS is parallelogram,
Opposite sides are congruent , i.e QR =PS & PQ = RS
NOW EQUATING THE SIDES,
⇒ 4x - 15 = 3x +5
⇒ x = 20
Answer: I did them with letters went from a to j but same order .
Step-by-step explanation:
Hi , idk if you know how to resolve those or you just was bored so in the first one I did firstly started by exchanging the letters and there number so , I wish it helped you at least a little more, bye good luck in life , you gonna be amazing : )
B. -3 and 5
constants are the numbers without variables (the letters) and coefficients are the numbers with variables
the answer is
x=8y/3(1-8y)
y=3x/8(1+3x)
hope this helped l used cymath to solve this problem.
good day : )
