Answer:
Step-by-step explanation:
<1 = <5 Corresponding angles.
<5 + <6 = 180° Angles making up the same straight line are supplementary.
<1 + <6 = 180° <1 and <5 are equal.
<6 = 180° - <1 If we know <1 we can easily find six. It is <1s supplement.
(x + 4)(x - 4)
x2 - 4x + 4x - 16
x2 - 16
The statement above is False.
Answer:
Step-by-step explanation:
These exponential forms can be written into radicals very easily as long as you remember the rule: The denominator of the rational exponent serves as the index of the radical and the numerator serves as the exponent on the radicand. Let's look at a rational exponent. 3/4 4 would be the index on the radical (the number that sits in the little dip of the radical sign) and 3 is the power on the base. So
can be written in radical form as
![\sqrt[4]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E3%7D)
Let's do 3^3/2 in your problem. 2 is the index (which is a "normal" square root and you don't need to write a 2 there cuz it's understood that it's a 2 if nothing is there), and 3 is the power on the base, which in our case is a 3. Bases can be numbers OR letters.
![3^{\frac{3}{2}}=\sqrt[2]{3^3}=\sqrt{3^3}](https://tex.z-dn.net/?f=3%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%3D%5Csqrt%5B2%5D%7B3%5E3%7D%3D%5Csqrt%7B3%5E3%7D)
That does in fact have an actual number answer, but I don't think you are simplifying them yet, only learning to write them from one form to another, so there you go!
Answer:
ASA
Step-by-step explanation:
angle side angle
1. 7 + 15 + 12 + 5 + 5 + 10 = 54
54 x 2.5 = $135
The correct answer is $135
2. A^2 + 9^2 = 22^2
A^2 + 81 = 484
A^2 = 403
Square root of a and 403
A= 20.7
20.7 + 22 + 9 = 51.7
The correct answer is (3)
