Answer:A:3/24
Step-by-step explanation:
It’s basic math
Step-by-step explanation:
7.2 / (-8.1) / (-3.7) = Positive
A = (-7.2) / (-8.1) / (-3.7) = Negative
B = (-7.2) / (8.1) / (3.7) = Negative
Hence the answer is C, none of the above.
Answer: ![4y^{2}(2x-9y)^{2}](https://tex.z-dn.net/?f=4y%5E%7B2%7D%282x-9y%29%5E%7B2%7D)
Step-by-step explanation:
We have the following polynomial:
![(4xy-18y^{2})^{2}](https://tex.z-dn.net/?f=%284xy-18y%5E%7B2%7D%29%5E%7B2%7D)
This is a polynomial of the form
. Following this rule to expand it, we have:
![(4xy)^{2}-2(4xy)(18y^{2})+(18y^{2})^{2}](https://tex.z-dn.net/?f=%284xy%29%5E%7B2%7D-2%284xy%29%2818y%5E%7B2%7D%29%2B%2818y%5E%7B2%7D%29%5E%7B2%7D)
![16x^{2}y^{2}-144xy^{3}+324y^{4}](https://tex.z-dn.net/?f=16x%5E%7B2%7Dy%5E%7B2%7D-144xy%5E%7B3%7D%2B324y%5E%7B4%7D)
Applying common factor
:
![4y^{2}(4x^{2}-36xy+81y^{2})](https://tex.z-dn.net/?f=4y%5E%7B2%7D%284x%5E%7B2%7D-36xy%2B81y%5E%7B2%7D%29)
Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:
![4y^{2}(2x-9y)^{2}](https://tex.z-dn.net/?f=4y%5E%7B2%7D%282x-9y%29%5E%7B2%7D)
Answer:
1.39
Step-by-step explanation:
nearest hundredth is 9
therefore 1.39 ig
Answer:
x = 10, x = 124
Step-by-step explanation:
(5)
Since Δ JKL is isosceles then the base angles are congruent, that is
∠ LJK = ∠ LJG = 80° , thus
∠ JLK = 180 - (80 + 80) = 180 - 160 = 20
x = 20 ÷ 2 = 10
(6)
Since Δ PQR is equilateral, then each of its angles = 60°
∠QRS = 60° - 32° = 28°
Since Δ SQR is isosceles then base angles are congruent, then
∠ SQR = ∠ QRS = 28 , thus
x = 180 - (28 + 28) = 180 - 56 = 124
