Answer:
height of the tree is 30 feet
Step-by-step explanation:
a tree casts a shadow 42 feet long . at the same time, a person 5 feet tall casts a shadow 7 feet long.
shadow of a 5 feet tall person is 7 feet long
Let x be the height of the tree
shadow of a 42 feet tree is x feet long
Make a proportion
cross multiply
divide by 7 on both sides
x=30
So height of the tree is 30 feet
There's not much you can or should do here other than to "solve for d."
Subtract 22 from both sides. Then 22 - 22 - 28d = -12 - 22 = -34
Then -28d = -34, and d = -28 / (-34) = + 14/17 (answer)
Answer:
C
Step-by-step explanation:
Work backwards. You are given -3 , -30 for C. If you add -3 + 3 and the divide it by 2 , you get 0. If you add 8 + -20 and divide by 2 you get -6 , so the answer is C.
Answer :
To find the product of (x + 8)(x – 10)
We know that
(x + a)(x + b) = x2 + (a + b)x + ab
In the expression (x + 8)(x – 10)
a = 8
b = -10
a + b = 8- 10 = -2
ab = 8 × (-10) = – 80
Substitute the values in the above equation
(x + 8)(x – 10) = x2 + (8 – 10)x + 8 × (-10)
(x + 8)(x – 10) = x2 – 2x – 80.
Thank you !
