Answer:
-5 + -4 = -9
Step-by-step explanation:
-5 + -4 = -9
Start at 0.
You will need to move 5 spaces to the left (Negative numbers move to the left while positives go right).
And -4. Move 4 spaces left again. There you land at -9.
The plus sign is just to combine -5 and -4 together.
Thus the answer is:
-5 + -4 is -9.
Here’s why the other equations aren’t correct.
The first equation says “5 + 4 = 9”.
To represent this, you would move 5 spaces to the right (because the number is posititve.)
Then combine 4. Which you move 4 spaces to the right again. This leaves you at 9 instead of -9.
The second equation says “-5 + -9 = -14”.
To represent this, you would move 5 spaces to the left.
Then move 9 spaces to the left again. Which leaves you at -14.
Your final destination should be -9. Not anywhere else.
The first answer, the Data is the same as the answer
Step-by-step explanation:
Length = x-3
width = x+8
Area of the rectangle = 60 inch²
(x-3)(x+8)=60
x²+8x-3x-24=60
x²+5x-24=60
x²+5x-84=0
x²+12x-7x-84=0
x(x+12) - 7(x+ 12) =0
(x+12)(x-7)= 0
x= -12 or, x= 7
Measure of sides of rectangle can never be negative.
Answers:
Therefore,
x=7
Dimensions
length =7-3
=4 inches
width = 7+8
=15 inches
Answer:
60.6°
Step-by-step explanation:
Using trigonometry :
Opposite = Height of shadow = 42 feets
Adjacent = height of flagpole = 23.7 feets
Tan θ = opposite / Adjacent
Tan θ = height of shadow / height of flagpole
Tan θ = 42 / 23.7
Tan θ = 1.7721518
θ = tan^-1(1.7721518)
θ = 60.56
θ = 60.6°
