Answer:

The sum of of the polynomials (m + n + 3) + (m + n + 4) is<u> </u><u>2m + 2n  +7</u>

Step-by-step explanation:

The given expression is (m + n + 3) + (m + n + 4)

we need  to find the sum of this expression

so, first we add the similar terms

m + n + 3 + m + n + 4

first write the like term together and then constant,

⇒ m + m + n + n +3 + 4

⇒ 2m + 2n  +3 + 4

⇒ 2m + 2n  +7

Therefore, The sum of of the polynomials (m + n + 3) + (m + n + 4) is<u> </u><u>2m + 2n  +7</u>

How many x-intercepts does the graph of y = 2x^2 – 8x + 5 have?
nydimaria [60]
A graph of the equation shows the appropriate choice to be
  C. 2

_____
If you would rather, you can look at the value of the discriminant. For the equation y = ax²+bx+c, the discriminant (d) is
  d = b²-4ac
For your equation, this evaluates to
  d = (-8)²-4(2)(5) = 64 -40 = 24
When the discriminant is positive, the function has two real roots (2 x-intercepts). When it is zero, there is only one x-intercept, and when it is negative, there are none (the roots are complex).

The sum of the area of 2 circles is 80pi square meters. Find the length of a radius of each circle if one of them is twice as lo
IgorC [24]
80p=pr^2+p(2r)^2
80p=pr^2+4pr^2
80=r^2+4r^2
80=5r^2
16=r^2
r=4 for the smaller circle´s radius, and 8 is the larger circle´s radius.

Have a nice day, I hope this was helpful :D
