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

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.
When removing or placing a new slide on the stage of a microscope at 4x, 10x, or 40x magnification, the objective should be set to the lowest power (usually 4x) to ensure proper clearance and avoid damaging the slide or the objective lens. This allows for easier positioning of the slide and prevents potential collisions between the slide and the lens. Once the slide is securely in place, you can then switch to a higher magnification for detailed observation.
To focus a microscope from 4x to 40x, start by using the 4x objective lens. Position the slide on the stage and use the coarse focus knob to bring the specimen into view, adjusting the light as needed. Once focused, switch to the 10x objective lens, using the fine focus knob to sharpen the image. Finally, switch to the 40x lens, again using the fine focus knob for optimal clarity, ensuring not to use the coarse knob at this magnification to prevent damage to the slide or lens.

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
