(4x+3)(2x-5)

Help please 10 points

Step-by-step explanation:

hello :

(4x+3)(2x-5)=0

4x+3=0 or 2x-5=0

x= -3/4 or x=5/2

(4x+3)(2x-5) =  8x²-14x-15

Step-by-step explanation:

Given,

(4x+3)(2x-5)

To find the value of the given multiplication.

Formula

(a+b)(c+d)

= a(c+d)+b(c+d) = ac+ad+bc+bd

Now,

(4x+3)(2x-5)

= 4x(2x-5)+3(2x-5)

= 8x²-20x+6x-15

= 8x²-14x-15

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
