Answer:
x = 20°
Step-by-step explanation:
For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.
110° = 2x + 70°
40° = 2x
20° = x
_____
Similarly, ...
y = x + 70° = 20° +70°
y = 90°
Answer: The answer to this question is (2a-5)(2a+5)
Step-by-step explanation:
- Because first, you have to write the quadratic equation 4a^2-25 in exponential form
- Then, you calculate the product by multiplying the terms with equal exponents by multiplying their bases
(2a)^2-5^2
- And then last but not least, using a^2-b^2=(a-b)(a+b), factor the expression
(2a-5)(2a+5) and then there's your answer and your explanation!!!!!
The answer is 5 feet.
1/4 = 1.25/x
x = 4•1.25
x = 5
2) is correct. (-3) but the arrow will point to the right in the graph
3)Next we’re gonna add 2 on the right side then it becomes b>=0 closed circle arrow will point to the right.
4)multiply 2 by -1. Your answer is o<-2. For the graph open circle on -2 going the left.
5)add 2 to 3 you’re
