Answer:

-3x

Step-by-step explanation:

This just goes down to very little rules. X's (even though not seen) always has an invisible number behind it (1). X is by itself, so is one of itself. We dont put the number there as it is just extra work, but it is there. When you have -X, you have minus one of that X, so you have -1x. The question is kinda weird stated, but I believe it is -3x. If you were to plug in -1x as x (x=-1x) then the answer would be -3x^2. So up to how the question is stated.

Hey can you please help me!
melisa1 [442]

Answer:


Step-by-step explanation:

1) Tangent makes 90 degrees with the radius. Hence

a) Angle ABD = 90-angle BDC = 90-61.3 = 28.7

b) Triangle BCD is isosceles since tangents have equal length.

Hence angle BCD = 180-(61.3+61.3) = 57.4

c) Angle BDC = 57.4 (since triangle BCD is isosceles)

d) Angle BAC and Angle BCD are supplementary. Hence angle BAC = 122,6

-------------------------------------------

2) Arc length of minor arc BC = \frac{79.3}{360} (24) = 5.287

b) ARc length of minor arc = circumference -minor arc

= 18.713

---------------------------------------------

3) circumference = pi d = 3.14(9) = 28.26

Two squares have sides 12cm and 4cm respectively. What is the ratio of their sides​
Nookie1986 [14]

Answer:

3 : 1

Step-by-step explanation:

We have to compare the value of two sides.

Ratio of sides = 12 : 4 = \dfrac{12}{4}=\dfrac{4*3}{4*1}=\dfrac{3}{1}

                       =  3 : 1
