f(x) = x-9 ;

g(x) = 3x²-2x +5

h(x) = -6x

A : f+g = x-9 +3x²-2x+5

f+g = 3x²-x-4

b : h-g = -6x - 3x²+2x-5

h-g = -3x²-4x-5

What is the answer to x+36=4x

rosijanka [135]

The answer is the number that 'x' must be in order for
that equation to be a true statement. Here's one way
to find out what the number is:

x + 36 = 4x

Subtract 'x' from each side: 36 = 3x

Divide each side by 3 : 12 = x

A horseback riding trail is 1 mi 40.8 ft long. How long is the trail in yards, feet, and inches?

ch4aika [34]

Answer: 1773.6 yards 5320.8 feet 64324.8 inches

Step-by-step explanation:

1 mile in yards = 1760 40.8 feet in yards = 13.6 1760 + 13.6 = 1773.6 yards

1 mile in feet = 5280 + 40.8 = 5320.8 feet

1 mile in inches = 63360

40.8 feet in inches = 964.8

63360 + 964.8 = 64324.8 inches

hope this helps :)

Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?

kolbaska11 [484]

Answer:

See Explanation

Step-by-step explanation:

Given

$Allen = \frac{3}{4}hr$ less than the most hour

Required

Hours read by Miss Allen

The question is incomplete, as the hours read by each student is not given.

To solve this, I will assume that the longest hours read by a student is x.

So, the expression for Miss Allen will be:

$Allen = x - \frac{3}{4}hr$

Assume that $x = 1hr$

The expression becomes

$Allen = 1hr - \frac{3}{4}hr$

Take LCM and solve

$Allen =\frac{4 - 3}{4}hr$

$Allen =\frac{1}{4}hr$

Sever21 [200]

Answer: they do not have enough info but I will try my best to answer if im wrong its not my fault so please add more info

Solution

2. I know that for a Semi-Circle Area = 320 . From this find out Area of the Semi-Circle.

Solution:

Here Area=320(Given)

Area=

πr2

r2=

Area⋅2

r2=

320⋅2

r=14.2701

Diameter(d)=2r

=2⋅14.2701

=28.5402

Circumference=πr

⋅14.2701

=44.849

Perimeter=πr+2r

⋅14.2701+2⋅14.2701

=44.849+28.5402

=89.6979
