3(x-5)-4(x+3)
Multiply the first bracket by 3
(3)(x)=3x
(3)(-5)=-15
(-4)(x)=-4x
(-4)(3)=-12
3x-15-4x-12
3x-4x-15-12 ( combine like terms)
Answer: -x-27
10x^2y^-2 = 10 x (-1)^2 x (-2)^-2 = 10 x 1 x 1/4 = 10/4 = 2 1/2
Answer:
(0,2)
Step-by-step explanation:
u have to graph the equation on paper
4, 16, 64, 256. The powers are 4 to the first. Four to the second, four to the third and four to the fourth power.
40 is an acute angle.
30 is an acute angel.
110 is an obtuse angle.
The easiest way to remember is anything below 90° (which is a right angle) is acute (think, cute = small). Anything above 180° is obtuse.
