Answer:
a
Step-by-step explanation:
Let x is the first no. then the other no. will obviously be (x+1)
according to question,
(x+1)²- x²= 15
x² +2x+1 - x² = 15 ( using (a+b)²= a²+ b² + 2ab )
2x + 1 = 15
2x = 14
x = 7
hence numbers are x = 7 and x +1 = 7+1 = 8
also 8²-7² = 64-49 = 15
hence the numbers are 7 and 8
hope it helped
Answer:
35:40 ; 35 to 40 ; 35/40
Step-by-step explanation:
Answer:
G = -4x - 4
x = -1
Step-by-step explanation:
step 1: flip your equation and turn G into zero
ex: -4x - 4 = 0
step 2: add 4 to both sides
ex: -4x - 4 + 4 = 0 + 4 (-4x = 4)
step 3: divide both sides by -4
ex: -4x/-4 = 4/-4 (x = -1)
step 4: plug -1 into x then solve to check your answer
ex: -4(-1) - 4 = 0
4 - 4 = 0
0 = 0 (when this says 0 = 0 then that means your answer is always true)
AB + BC = AC <em>Segment Addition Postulate</em>
(x + 10) + (x + 14) = 22 <em>Substitution</em>
2x + 24 = 22 <em>Simplify (added like terms)</em>
2x = -2 <em>Subtraction Property of Equality</em>
x = -1 <em>Divison Property of Equality</em>
Answer: x = -1
