Answer:
there are two terms which means it is a binomial algebraic expression
Step-by-step explanation:
the first term is -9
and the second term is 5.5
note:be aware that the negative sign is there in the first term and the reason that we didn't put the negative sign in the second is because there is no negative sign before 5.5 .
I'm guessing the total amount of degrees is 360 degrees.
67 + 130 + 72 = 269
360 - 269 = 91
Answer = 91°
Hope this helped☺☺
Answer: x = - 3.5
Step-by-step explanation:
Rewrite the equation by completing the square.
4x2 + 28x + 49 = 0
Completing the square method :
Divide through by the Coefficient of x^2
x^2 + 7x + (49/4) = 0
a = 1, b = 7, c = 49/4
Move c to the right side of the equation
x^2 + 7x = - 49/4
Complete the square on the left hand side by squaring its half of the x term
(7/2)^2 = (49/4)
Add the output to both sides of the equation
x^2 + 7x + (49/4) = - (49/4) + (49/4)
(x + 7/2)^2 = 0
Square root of both sides
x + 7/2 = 0
x = - 7/2
x = - 3.5
