Answer:
Z = 2
Step-by-step explanation:
This tape diagram is split into two equal parts.
Since 2 and 2 are equal, and since 2 and 2 have a sum of 4, then z is equal to 2.

Answer:
825.663706143591cm
Step-by-step explanation:
80cm × 4 = 320cm
100cm × 3 = 300cm
The radius is 40
40 × 2 = 80cm
Circumference is πd
π80 = 251.327412287183
÷ 2 = 125.663706143591cm
In total
320 + 300 + 80 + 125.663... =
825.663706143591cm
Answer:
B. x = -8
Step-by-step explanation:
-4(2x + 3) = 2x + 6 - (8x + 2)
-8x -12 = 2x + 6 - 8x -2
(now, "-8" in both terms is cancelled):
-12 = 2x + 6 - 2
(leave 2x alone in second term):
-12 -6 +2 = 2x
-16 = 2x
-16/2 = x
-8 = x
15m ^3 - 26m^2 +11m - 4 is the result of the product.
(5m^2 -2m +1)(3m-4)
On opening the bracket, we multiply the terms,
= 15m^3 -6m^2 +3m -20m^2+8m -4
= 15m ^3 - 26m^2 +11m - 4
This is the result of the product
When we mutiply the two equations.
