Answer:
y intercept=15 and slope is 3
Step-by-step explanation:
Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15
to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:
(18-15)/(1-0)
3/1
= 3

Answer:
Breadth = 10 cm
Length = 15 cm
Step-by-step explanation:
Let the breadth = x cm
Length = (x + 5) cm
Perimeter of a rectangle = 50 cm
2 *( length + breadth) = 50
2*(x + 5 + x) = 50
Combine like terms
2*(2x + 5) = 50
2*2x + 2*5 = 50
4x + 10 = 50
Subtract 10 from both sides
4x = 50 - 10
4x = 40
Divide both sides by 4
x = 40/4
x = 10
Breadth = x = 10 cm
Length = x +5 = 10 + 5 = 15 cm
Estimation is lazy math
first round 5.2 to 5
5 times 12 = 60
product is actual math
12 times 5.2 = 62.4
