Answer:
(a) 6² +3² +1² +1² = 47
(b) 5² +4² +2² +1² +1² = 47
(c) 3³ +4² +2² = 47
Step-by-step explanation:
It can work reasonably well to start with the largest square less than the target number, repeating that approach for the remaining differences. When more squares than necessary are asked for, then the first square chosen may need to be the square of a number 1 less than the largest possible.
The approach where a cube is required can work the same way.
(a) floor(√47) = 6; floor(√(47 -6^2)) = 3; floor(√(47 -45)) = 1; floor(√(47-46)) = 1
__
(b) floor(√47 -1) = 5; floor(√(47-25)) = 4; ...
__
(c) floor(∛47) = 3; floor(√(47 -27)) = 4; floor(√(47 -43)) = 2
I believe the Slope- intercept formula is y = mx + b
Slope is your m = -4
Point: (2, -4)
x = 2
b is your y-intercept = -4
Answer: y = -4(2)+ -4 or -4(2)-4?
So sorry if it’s wrong but I hope this helps
Answer:
62
Step-by-step explanation:
Step 1:
50 ÷ 2 + 5 × 10 ÷ 2 + 7 Equation
Step 2:
25 + 5 + 50 ÷ 2 + 7 Divide 50 by 2 and Multiply 10 by 5
Step 3:
25 + 5 + 25 + 7 Divide 50 by 2
Step 4:
30 + 25 + 7 Add
Step 5:
55 + 7 Add
Answer:
62
Hope This Helps :)
