Answer:
a. (5x+2)(5x+2)
Step-by-step explanation:
You will recognize that the first (25x^2) and last (4) terms are perfect squares. The middle term is double the product of the roots of those squares:
2(5x)(2) = 20x
This means the given expression is a perfect square trinomial, and that it is the square of (5x+2). This matches the first choice.
25x^2 +20x +4 = (5x +2)^2 = (5x +2)(5x +2)
_____
Generically, ...
(a +b)^2 = a^2 +2ab +b^2
Here, we have a=5x, b=2.
There's not options but:
-All sides are the same length
-Each side is about 11 inches
(x - 2 < 5) ∩ (x + 7 > 6)
Let's resolve each one
x - 2 < 5
x < 5 + 2
x < 7
x + 7 > 6
x > 6 - 7
x > -1
So we have 2 conditions: x > -1 and x < 7 plus, we need the values that's equal in x < 7 and x > -1 because we have an intersection
S = {x e R / -1 < x < 7}
Answer:
37
Step-by-step explanation:
1. Subtact 152 from 180 because 152 and the angle next to it are corresponding
180 - 152 = 28
2. Add the two angles inside the triangle and subtract them from 180 to find the missing angle
28 + 115 = 143
180 - 143 = 37
angle 1 = 37
