How do you multiply the expression (3x+2)(4x-7)
Leona [35]

Answer:

You "FOIL" (First, Outer, Inner, Last).

12x^{2}  - 13x - 14

Step-by-step explanation:

You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.

(3x+2)(4x-7)

(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)

12x^2 - 21x + 8x - 14

12x^2 - 13x - 14

The interior angles of a quadrilateral are 2x+15 2x-5 3x+75 3x-25 find x and the smallest interior angle largest interior angle
BartSMP [9]

Answer:x=30^{\circ}

Step-by-step explanation:

We know sum of the interior angles of a quadrilateral is 360^{\circ}

therefore  we can write

(2x+15)+(2x-5)+(3x+75)+(3x-25)=360^{\circ}

so

\Rightarrow 10x+60=360

\Rightarrow 10x=300

\Rightarrow x=30^{\circ}

So smallest interior angle is (2x-5)^{\circ}=(60-5)=55^{\circ}

Largest interior angle =3x+75=90+75=165^{\circ}
