S = 1 /78k -1/4
idk equation but i do know an answer has to be sue bottle holds 1 20/32
1 28/32
8/32
sorry if i get this wrong on you but i tried
Answer:
1. x^2-36
X^2-6^2
(X-6)•(x+6)
3. 16y^2-25
4^2 Y^2-5^2
(4y)^2-5^2
(4y-5)•(4y+5)
5. 9a^2-121
3^2 a^2-11^2
(3a)^2-11^2
(3a-11)•(3a+11)
6. 196-x^2
14^2 -x^2
(14-x)•(14+x)
8. 36c^2-d^2
6^2 c^2 -d^2
(6c)^2-d^2
(6c-d)•(6c+d)
11. 1-4a^2
1^2- 2^2 a^2
1^2-(2a)^2
(1-2a)•(1+2a)
A. An obtuse angle is less than 180 but greater than 90. So for examples sake I will use 179 degrees. 179 divided by 2 (as the angles are congruent) = 89.5 which is less than a right angle. Therefore, the angles will be acute.
Hope it helps :)
Answer:
-1.5
Step-by-step explanation:
4x² + 4x - 3 = 0
(2x + 3)(2x - 1) = 0
2x + 3 = 0 or 2x - 1 = 0
x = -3/2 or x = 1/2
Answer: -1.5
The answer is C. y = - 2x - 1
hope that helps!! :)
