Answer:
1.x^2-5x
2.2x^2+15x+18
3. x^2+20x+18
Step-by-step explanation:
1. x(x-5) x*x-5*x = x^2-5x
2. (x+6)(2x+3) x*2x+x*3+6*2x+6*3= 2x^2+15x+18
3.(2x^2+15x+18)-(x^2-5x)=x^2+20x+18
Answer:
7.57 cm
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
r= radius
h = height
1,800 = 3.14 x r² x 40
r² = 1800 /(3.14 x 40)
r² = 14.33121
√14.33121 = r
r = 3.785658 cm
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
Diameter = 2 x 3.785658 cm = 7.57cm
The cups of water should be:
2 x 12 = 24 ( cups of water )
Answer:
thirteen sixteenths
Step-by-step explanation:
Three eighths plus seven sixteenths equals blank
3/8 + 7/16 = ?
= (2*3)+(1*7)/16
= (6+7)/16
= 13/16
13/16 is equivalent to thirteen sixteenths
