Answer: 2x^2-7x-15
Step-by-step explanation:
reorder the terms (x*2+3)*(x-5)
multiply the parentheses
(2x+3)*(x-5)
collect like terms (2x^2-10x+3x-15)
product= 2x^2-7x-15
Answer:
Answer is 6/10 and 12/20
Step-by-step explanation:
Let the numerator be x.
3/5=x/10
x=30/5
x=6
The required fraction is 6/10
Now same method applies for taking 20 as denominator
3/5=x/20
x=60/5
x=12
The required fraction is 12/20
A.) 14/15 B.) 17/14 C.) 5/12
Step-by-step explanation:
BDC and ACD are complementary with each other. that means together they cover the full 180 degrees of the half circle that can be drawn on one side of a flat line.
180 = 11x + 25 + 4x + 5 = 15x + 30
150 = 15x
x = 10
BDC = 11x + 25 = 11×10 + 25 = 110 + 25 = 135 degrees
ACD = 4x + 5 = 4×10 + 5 = 40 + 5 = 45 degrees
