The area of a triangular flower bed in the park has an area of

blagie [28]

Answer:

b = 24 ft

h = 10 ft

Step-by-step explanation:

120 = ½hb

120 = ½h(3h - 6)

240 = h(3h - 6)

240 = 3h² - 6h

80 = h² - 2h

0 = h² - 2h - 80

0 = (h - 10)(h + 8)

h = 10 ft or -8 ft

we ignore -8 as it makes no sense for a triangle side length.

b = 3(10) - 6 = 24 ft

Which expression belongs in the box?

MakcuM [25]

Answer:

The expression that belongs in the box is 8 x 4

Option C is correct answer.

Step-by-step explanation:

We need to find Which expression belongs in the box?

$(3 \times 8) \times 4= 3 \times (------)$

The property applied here is associative property of multiplication.

Associative property of multiplication states that:

$(a \times b)\times c = a \times (b \times c)$

So, if we apply the property to our question we have:

a = 3

b = 8

c = 4

So, the expression will become: $(3 \times 8) \times 4= 3 \times (8 \times 4)$

So, the expression that belongs in the box is 8 x 4

Option C is correct answer.

PLEASE HELP MEEEEEEE!!!!!

umka2103 [35]

Answer:

C 7ft/yr

Step-by-step explanation:

The given points are not all on the same line, so the average will vary depending on the interval of interest.

Over the interval [1, 11] years, the average rate of change of height is ...

change in height / change in years = (80 -10)/(11 -1) = 70/10 = 7 . . . ft/yr

On the interval [11, 15] years, the average rate of change is ...

(105 -80)/(15 -11) = 25/4 = 6.25 . . . ft/yr

Even on this interval, the closest answer choice is C.

Please help!! I'm very confused

Tom [10]

Answer:

b+7

Step-by-step explanation:

To simplify an equation, you combine like terms and remove redundancies. Like terms are 4b and 3b, another pair of like terms are 9 and 2. Let's combine them. 4-3 is 1, so we can make the equation into 1b+9-2. We can simplify that to b+9-2. But wait, we can combine 9 and 2. 9-2 is 7, so the final simplified equation is b+7. I hope this helps!
