Two integers a and b have a product of -33. What is the least possible sum of a and b

irga5000 [103]

The number -33 divisors are:

D(-33) = {-33, -11, -3, -1, 1, 3, 11, 33}

a × b = -33

1) -33 × 1 = -33 ⇒ Sum is: -33 + 1 = -32

2) -11 × 3 = -33 ⇒ Sum is: -11 + 3 = -8

3) -3 × 11 = -33 ⇒ Sum is: -3 + 11 = 8

4) -1 × 33 = -33 ⇒ Sum is: -1 + 33 = 32

5) 1 × (-33) = -33 ⇒ Sum is: 1 + (-33) = 1 - 33 = -32

6) 3 × (-11) = -33 ⇒ Sum is: 3 + (-11) = 3 - 11 = -8

7) 11 × (-3) = -33 ⇒ Sum is: 11 + (-3) = 11 - 3 = 8

8) 33 × (-1) = -33 ⇒ Sum is: 33 + (-1) = 33 - 1 = 32

<h2>The least possible sum of a and b is -32</h2>

Suppose the lengths of two sides of a right triangle are represented by 2x and 3 (x + 1), and the longest side is 17 units. Find

densk [106]

Answer:

x=4

Step-by-step explanation:

Step 1:-

given the lengths of two sides of a right angle are represented by 2x and 3(x+1) and longest side is 17 units.

AB = 2x and BC = 3(x+1) and longest side AC= 17

by using Pythagoras theorem

$AC^2 = AB^2 + BC^2$

step 2:-

The hypotenuse is longest side is AC = 17 units

(17)^2 = 4x^2 +9(X+1)^2

on simplification, we will use formula

$(a + b)^2 = a^2 +2ab+b^2$

289 = 4x^2 +9(x^2+2x+1)

$13x^2 +18x-280 = 0$

finding factors 70 X 52 = 3640

$13x^2 +70x-52x-280 = 0$

$13x^2 -52x+ 70x-280 = 0$

Taking common , we get

13x(x-4)+70(x-4)=0

x-4=0 and 13x+70=0

x=4 and $13x =-70$

x=4 and $x=\frac{-70}{13}$

we can not choose negative value so x value is 4

Final answer:- x = 4

verification:-

$AC^2 = AB^2 + BC^2$

289 = 4(4)^2+9(4+1)^2

289 = 64 +9(25)

289=289

Find the solution to t - (-2) = 6.

Alex_Xolod [135]

t - (-2) = 6
t + 2 = 6
subtract 2 to both sides
t + 2 - 2 = 6 -2
simplify
t = 4
