Answer:
length = 12 feet and width = 8 feet
Step-by-step explanation:
since the area = 96 ft² then
(x + 1)(x - 3) = 96 ( A = lw )
expand the factors on the left side
x² - 2x - 3 = 96 ( subtract 96 from both sides )
x² - 2x - 99 = 0 ← in standard form
(x - 11)(x + 9) = 0 ← in factored form
equate each factor to zero and solve for x
x - 11 = 0 ⇒ x = 11
x + 9 = 0 ⇒ x = - 9
but x > 0 ⇒ x = 11
length = 11 + 1 = 12 feet and width = 11 - 3 = 8 feet
Answer:
equivalent to what? is there a missing picture?
Step-by-step explanation:
Answer:
a)4080 trees
b)104 trees
Step-by-step explanation:
<u>1st - 24 trees</u>
<u>last (40th) - 180 trees</u>
If differences between any row (except 40th) and next row are equal then
<u>2nd - 24 trees+X</u>
<u>3rd - (2nd+X) or 24 trees + 2X</u>
coefficient of X is <u>number of row minus 1</u>, therefore 40th row has <u>24 trees + 39X</u>, and it is equal to <u>180</u>. We can make an equation from this:
<u>24tr+39X=180tr</u>
<u>39X=156tr</u>
<u>X=4tr</u>
By this we can find how many trees are there in the 21st, 21st row has 24 trees+20X=24 trees+80 trees=104 trees
To find how many trees are there in the whole orchard, we add them all:
<u>1st - 24 trees, 2nd - 24 trees + X, 3rd - 24 trees + 2X,</u>
easily, it is just <u>24 trees x 40 + 39X x 20 = 4080 trees</u>
Answer:
Step-by-step explanation:
29,484
4, Does not round
the second 4, rounds to 5 because of the 8,
then The 9 would round and be 30
if its a decimal then it would be 30.0
if not then i think it would be 30,500 or 29,500 if we were to stop at the 9 and not round it
Answer:
A: 3n + m + 2p
Step-by-step explanation:
4n - m + 3p + 2m - n - p
4n - n + 3p - p + 2m - m
3n + 2p + m
3n + m + 2p
