Since 1 km = 1000 m, the lawnmowers top speed would be 8000 m/h.
Okay so a couple of things to know to best solve this problem
1) all angles in a triangle add to 180
2) a straight line the angles above it equal 180 and the angles below it add to 180
3) vertical angles are equal (vertical angles are angles that make an X the opposite angles are called vertical angles)
Answer:
Step-by-step explanation:
1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7
2)Subtract 7 from both sides
4x+7=39
-7 -7
4x=32
3) Divide by 8
x=8
Thus we get x=8 as answer
So reasons are
i) Distributive property
ii) Subtraction property of equality
iii) Division property of equality
Answer:
-5
Step-by-step explanation:
At first,
f(-1) = 3 x (-1)² + 5 x (-1) -7
= 3 - 5 - 7
= -9
g(f(-1)) = g(-9)
= 2 x (-9) + 13
= -18 + 13
= -5
