10% and 16% ? I think I haven't done this in three years!
Answer:
71
Step-by-step explanation:
Add 5 to 11 and then keep adding 5 to every number after that until you get your answer
Lets get started :)
x² - 7x + 10
We are going to find something in this form:
↓
( )( )
x² is nothing but x multiplied by itself
↓
(x )(x )
-7x + 10 follows
since the sum is negative and the product is positive then the signs inside the bracket will be as follows
↓
( x - )( x - )
-7x should be the sum and 10 should be the product
multiples of 10 = 1 x 10 = 2 x 5 = -1 x -10 =
-2 x -5 ↓ ↓ ↓ ↓
1 + 10 = 11 2 + 5 = 7 -1 - 10 = -11 =
-2 -5 = -7
So the sum of -2 and -5 is -7 and the product of -2 and -5 is 10
↓
( x - 2 )( x - 5 )
Your final answer will be
option B
Answer:
B
Step-by-step explanation:
The volume (V) of a triangular prism is
V = area of triangular end × length
area of Δ = bh
where b is the base and h the perpendicular height
here b = 8 and h = 5, so
area = 0.5 × 8 × 5 = 20 units²
the length of the prism is 10, hence
V = 20 × 10 = 200 units³
