Step-by-step explanation:
Answer:
they are proportional
Step-by-step explanation:
4:6 simplified is 2:3
(divide 4 and 6 by 2 which would be 2:3)
Answer:
blank 1: 2xy(4x-5y)+3(4x-5y)
blank 2: (2xy+3)(4x-5y)
Step-by-step explanation:
Using factoring group to factor the polynomial 8x²y−10xy²+12x−15y
Step 1: Group the polynomial function
(8x²y−10xy²)+(12x−15y)
Step 2: Factor the common value and variables from the functions in parentheses.
= (2xy*4x - 2xy(5y)) + (3(4x) - 3(5y))
= 2xy(4x-5y)+3(4x-5y)
Step 3: Rearrange the expression by selecting one of the function in parentheses and combine those not in parenthesis.
(2xy+3)(4x-5y)
The final expression gives the factor form of the polynomial.
Hence the statement for each blank that correctly completes Lana's work are;
blank 1: 2xy(4x-5y)+3(4x-5y)
blank 2: (2xy+3)(4x-5y)
Since it's a square, all sides are equal
therefore,
3x - 5 = x + 1
2x = 6
x = 3
sub x into AD, which is 3x-5
= 3(3) - 5
= 9 - 5
= 4
therefore AD is 4 units
