Answer:
28
Step-by-step explanation:
32 - 9 = 23,
24 + 4 = 28
Answer:
- 2x + y = - 1 , so the B is correct.
Step-by-step explanation:
+ Because of "the line passing through the pair of points (2,3) and (5,9)", that means the line has the equation y = ax + b where a = (9-3)/(5-2)= 6/3= 2
+ So the equation is y = 2x + b.
+ Then we replace x= 2 and y= 3 into y = 2x + b for finding like:
3 = 2*2 + b or 3 = 4 + b, so we find b = 3 - 4 = - 1.
+ The equation of this line is y = 2x - 1 or in the form:
2x - y - 1 = 0 (or -2x + y = -1)
Have a good day!

Answer:
294cm²
Step-by-step explanation:
Given the formula for surface area expressed as 6L^2
TSA = 6L²
Given that L = 7cm
Substitute
TSA = 6(7)²
TSA = 6 * 49
TSA = 294cm²
<em>Hence the total surface area is 294cm²</em>
