Use inverse operations to solve X - 5.6 = -1.7

DedPeter [7]

The inverse operation of subtraction is addition. Lets use the inverse operation to solve x. Lets do it:-

x - 5.6 = -1.7
-1.7 + 5.6 = x
-1.7 + 5.6 = 3.9
x = 3.9

CHECK OUR WORK:-

3.9 - 5.6 = -1.7
We were RIGHT!!

So, x = 3.9.

Hope I helped ya!!

Given the trinomial, what is the value of the coefficient B in the factored form? 2x2 14xy − 36y2 = 2(x By)(x − 2y) 18 9 −9 −18.

Finger [1]

The value of the coefficient B will be 9.

<h3>What will be the value of B in equation written below?</h3>

2(x+By)(x-2y)

=2(x^2 -2xy +Bxy -2By^2)

=2x^2 -4xy + 2Bxy - 4By^2

The original form is $\d2x^{2} +14x-36y^{2}$

$2(x+By)(x-2y)\\\ =2(x^2 -2xy +Bxy -2By^2)\\\\ =2x^2 -4xy + 2Bxy - 4By^2\\\\2x^2 + 14xy - 36y^2\\\\ -36y^2 = -4By^2B= 9\\\\ -4xy +2Bxy= 14xy\\\\xy(-4 +2B)= 14xy\\\\ -4 + 2B = 14\\\\ 2B = 18\\\ B=9$
