Hello from MrBillDoesMath!
Answer:
Choice C
Discussion:
(f+g)(x) = f(x) + g(x)
= (3x + 5) + x^2
= x^2 + (3x + 5) by the commutative property
which is choice D
Thank you,
MrB
If you would like to know the value of 'c' in the quadratic equation, you can find this using the following steps:
3x^2 + 5x + 7 = 0
ax^2 + bx + c = 0<span>
a = 3
b = 5
c = 7
The correct result would be 7.</span>
The solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have an inequality:
−14a ≥ 42
-a ≥ 3
a ≤ -3
a ∈ (-∞, -3]
Thus, the solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

Answer:
119°
Step-by-step explanation:
the angles of a triangle make 180° (so does a straight line) therefore
180 (triangle) = a + c + 51
to find c:
180 (straight line) = 112 + c
c = 180 - 112
c = 68°
now we have
180 (triangle) = a + 68 + 51
to find a:
a = 180 - (68 + 51)
a = 180 - 119
a = 61°
to find b:
180 (straight line) = 61 + b
b = 180 - 61
b = 119°
