Answer:
B) -12.4 + 20.6s
Step-by-step explanation:
width = (3.1s - 1.6) cm
Length = (7.2s - 4.6) cm
Perimeter of rectangle = 2* (length +width)
= 2 *(7.2s - 4.6 + 3.1s - 1.6) {add like terms}
= 2* (<u>7.2s + 3.1s</u> - 4.6 - 1.6)
= 2*( 10.3s - 6.2) {distributive property}
= 2*10.3s - 2*6.2
= 20.6s - 12.4
Answer:
(2,-3) + (1,-2)
Step-by-step explanation:
Answer:
3x + 4y +8 = 0
Step-by-step explanation:
(X1,Y1) = (4,0)
(X2,Y2)=(0,3)
(X3,Y3)=(0, - 2)
Slope(m)=(Y2-Y1)/(X2-X1)
= (3-0)/(0-4)
= -3/4
Equation of the line,
Y-Y3 = m(X-X3)
Y-(-2)= (-3/4) × (X-0)
Y+2= (-3/4)X
Y+2= -3X/4
4(Y+2)= -3X
4Y+8= -3X
4Y+3X+8=0 is the required equation.
Answer:
5 lines
Step-by-step explanation:
5 times 5 is 25 so 25 divided by 5 is 5 therefor your answer is 5
To get the average in this case, divide 30 by 5:
30 hrs ÷ 5 days = 6 hrs/day
