Well 4*-3 =-12 but then multiply that by five you will get -60

To simplify this, the only thing we have to do is multiply all the quantities together. Since they are all connected by multiplication, it doesn't matter in which order we do it. Therefore, it might be helpful to multiply 4 and 5 first (because then we have a number with a zero at the end of it). 4 * 5 is 20. Now the expression is 20 * -3. 20 * 3 is 60, but 20 * -3 is -60 (because a positive number times a negative number is negative). That means that the answer is -60.

What factors multiply to -80 and add to 6

forsale [732]

80 = -1(80), -2(40), -4(20), -5(4),

Total answers include: -81, 79, -42, 16, -9, and 1.

None of them add up to 6!

Are you doing polynomial equations?

If so, you can solve it the hard way.

x^2 + 6x -80 = 0

(x^2 + 6x + 9) - 80 = 9

(x+3)^2 = 89

(x+3) = 9.43

x = 6.43

If you're not doing those then I'm afraid your question has no answer.

Hope that helps!

Zielflug [23.3K]

Answer:

See below ~

Step-by-step explanation:

Question 1

The missing angles

Both the unknown angles have the same value as the other two angles in the triangles are the same
∠(missing) = 180 - (72 x 2)
∠(missing) = 180 - 144
∠(missing) = 36°

⇒ The sides are equal

⇒ Angles are not 90°

⇒ It is a rhombus

Question 2

The diagonals of the shape bisect other (Statement 1)
NY = NW (given)
XN = NZ (given)
∠XNY = ∠WXZ (vertically opposite angles)
ΔXNY ≅ ΔWXZ (SAS)
They form two congruent triangles (Statement 2)
From these two statements, it is evident the figure is a parallelogram
