Answer:
Answer options
A. Two cities that are 7.5 cm apart on the map are actually 50 km apart.
D. Two cities that are actually 66 km apart are 9.9 cm apart on the map.
Step-by-step explanation:
Step 1
Indicate the scale as shown;
3 cm : 20 km, meaning 3 cm on the map represents 20 km on the ground
A). what does 7.5 cm represent on the ground
Distance on ground=(7.5×20)/3=50 km
B). what does 4 cm represent on the ground
Distance on ground=(4×20)/3=26.67 km
C). what does 45 km on ground represent on the map
Distance on map=(45×3)/20=6.75 cm
D). what does 66 km on ground represent on the map
Distance on the map=(66×3)/20=9.9 cm
- Rounding 789 nearest to tens will be 790.
Step-step Explanation:
Let's know how to round any number nearest to tens (Rules):-
We know tens place in any no. from left is at second place and number right to tens place need to be changed as:-
- If last digit is 0, then we don't have to do any rounding, because it is already to the ten.
- We round the no. down to the nearest ten if the last digit in the no. is 1, 2, 3, or 4
- We round the no. up to the nearest ten if the last digit in the no. is 5, 6, 7, 8, or 9.

Answer:
The answer is
<h2>(9x - 4)(4x + 3)</h2>
Step-by-step explanation:
36x² + 11x - 12
To factor the expression rewrite 11x as a difference
That's
36x² + 27x - 16x - 12
<u>Factor out 9x from the expression</u>
9x( 4x + 3) - 16x - 12
<u>Factor out - 4 from the expression</u>
9x( 4x + 3) - 4( 4x + 3)
Factor out 4x + 3 from the expression
We have the final answer as
<h3>(9x - 4)(4x + 3)</h3>
Hope this helps you
