-376+-3=? <br><br>and how do i get my couculater to subtract negative numbers

nikitadnepr [17]

Well you could think of this like this
-376+-3, is the same as adding with negatives, instead of adding with positives, like 376+3, we are only changing the sign in front of it. So instead of it being equal to 379, -376+-3 = -379.

Robert can mow a 600 square lawn in 1 hour and 20 minutes. How many lawns in the same size's can he mow in 8 hours?

adell [148]

First off change everything to minutes. The 600 is irrelevant in this problem. He can mow this size in 80 minutes. 8 hours is 8x60= 480. 480/80 is 6 and therefore he can mow 6 lawns in this size in time of 8 hours

Solve 2x^2– 5= 3x with the quadratic formula

Gwar [14]

Answer:

see below

Step-by-step explanation:

2x^2-3x-5=0

Well a=2, b=-3, c=-5

$x=\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)} }{2*2}\\\\ x_1=\frac{3+\sqrt{49} }{4} =\frac{3+7}{4} =\frac{10}{4} =\frac{5}{4} \\\\x_2=\frac{3-\sqrt{49} }{4} =\frac{3-7}{4}=\frac{-4}{4} =-1$

3(x+2)=2(2x+7) help meeeeeeeeeeeeee

forsale [732]

Use distributive property

3(x + 2) = 2(2x + 7)

(3)(x) + (3)(2) = (2)(2x) + (2)(7)

3x + 6 = 4x + 14 |subtract 6 from both sides

3x = 4x + 8 |subtract 4x from both sides

-x = 8 |change the signs

What can be concluded about the polygon?

cupoosta [38]

You can conclude that the sides are parallel because the slope of the opposites are the same. (Second option).

You can conclude that the polygon is a rectangle since it has 4 90º angles, and 4 sides, each one parallel to the other and of the same lenght as it's parallel. (Last option).

Answer:

$\boxed{\bf~The~second~and~last~options~are~correct.}$

Hope it helped,

Happy homework/ study/ exam!
