Find two consecutive numbers whose squares differ by 25

1 answer:

5 0

Consecutive numbers means that they are one after the other (i.e. 1, 2, 3 are consecutive numbers). The square of a number signifies the product of this number times itself (i.e. 2 times 2 = 4, so 4 is the square of 2). If these squares differ by 25, then when they are subtracted from one another, the difference will be 25:

12 x 12 = 144
13 x 13 = 169

169 - 144 = 25

Scorpion4ik [409]

Answer:

x = 7 is the answer for the smaller number

7 + 1 = 8 is the answer for the larger number

Step-by-step explanation:

LET x and x+1 be the two numbers here, as your hint suggests.

5x + 3(x+1) = 59

5x + 3x+3 = 59

8x = 59-3

8x = 56

/8 /8

--------------------------

x = 56/8 ---> x = 7

x = 7 is the answer for the smaller number

7 + 1 = 8 is the answer for the larger number

Check:

5 * 7 + 3 * 8 = 59

35 + 24 = 59

59 = 59 CORRECT

Triangle XYZ is obtuse which list could represent the angle measures of triangle XYZ?

asambeis [7]

An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
