Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.
Answer:
M = 20(2) + 3(2) = $46
Step-by-step explanation:
Here, we want to write an equation that could be used to find the amount of money spent
The rental charges $20 for a day and $3 for an hour
For 2 days, amount is 2 * 20 = $40
for 2 hours , amount is 3 * 2 = $6 hours
The amount Spent M will be;
M = 20(2) + 3(2) = $46
Answer:
5 + 2(3 + 2x) = x + 3(x + 1) (2nd one)
Step-by-step explanation:
The top and bottom question's are all real numbers and the third one is 0
The formula is 1/2bh(h). multiply the base times the height then multiply that by the other height and divide the sum by two
