Answer:
(22, 9)
Step-by-step explanation:
The positive difference of two integers is 13. The sum of the larger number and the square of the smaller is 103. Give your solution(s) as ordered pair (larger, smaller). I'll call the two integers a and b.
a - b = 13 a + b² = 103
<u> +b +b</u>
a = 13 + b plug this into the second equation
a + b² = 103
(13+b) + b² = 103 subtract 103 from both sides to get one side equal to zero
<u>-103 -103</u>
b² + b - 90 = 0 what factors (two numbers multiply) to -90 that also add up
to 1? The only two that work are -9 and 10.
(b-9)(b+10) = 0 so b-9 = 0 or b+10 = 0
<u>+9 +9</u> or <u>-10 -10</u>
b = 9 or b = -10 but both numbers must be positive
b = 9 and a = 13 + b so a = 13 + 9 = 22

Answer:
pie is 3.14 so its dividing 64 by pie
Step-by-step explanation:
Remember d=rt
so its 3.5=r(0.5)
divide 3.5 by 0.5, which is 7. His rate is 7 miles per hour.
X^2 + 5x + 4
list the factors of 4 1*4 and 2*2
which of the factors add up to 5 1 + 4 = 5
(x + 1)(x + 4)
x^2 - 7x + 10
list the factors of 10 1*10 and 2*5
which of these factors add up to 7 2 + 5 = 7
since it is -7 it will be -2 + -5 = -7
(x - 2)(x - 5)
