To answer this question we would need to know the signs that go in between the numbers. For example if it was addition, multiplication, or an exponent.
If measure angle 3 = x2 + 4x and measure angle 5 = 3x + 72, find the possible measures of angle 3 and angle 5
blue
The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
five
The lower power objective for the microscope is the small lense on the microscope. The size usuall ranges at 4x on the microscope.
3x + y
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
Add likes to likes. A= 4x + 2y + 3z and B= -x + 7y + 0z, then A +B= 3x + 9y + 3z.
4x-2y+3x+2y When simplified: 7x
If you mean: 3x-(2x+4x-6) then 3x-2x-4x+6 simplifies to 6-3x
6x-2x-6xy-2x-2y4x-2y=2x-2y-14xy
(4x)(2y) would be factored as such: 4x = 2 • 2 • x 2y = 2 • y 2(2x)(y)
They are terms of algebraic expressions
4x + 2y = -8 → 2y = -4x - 8 → y = -2x - 4
2x-y=103x-2y=8Elimination:-4x+2y=-203x- 2y= 8+________-x = -12x=1224-y=10-y=-14y=14(12,14)
6x-2y
2y = 4x + 4y = 2x + 2
