How would you simplify <br>(3+i)(4+2i)?​
const2013 [10]

Answer:

<h2>(3 + i)(4 + 2i) = 10 + 10i</h2>

Step-by-step explanation:

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

and i² = -1

(3+i)(4+2i)\\\\=(3)(4)+(3)(2i)+(i)(4)+(i)(2i)\\\\=12+6i+4i+2i^2\qquad\text{combine like terms}\\\\=(12-2)+(6i+4i)\\\\=10+10i

One angle of an isosceles triangle measures 100°. which other angles could be in that isosceles triangle? choose all that apply.
antoniya [11.8K]
Both of the other angles are 40° because a triangle has a total angle of 180° and an isosceles triangle means that at least two of the sides have to be the same length (two angles must be the same)
180 - 100= 80
80 ÷ 2 = 40

Mara simplifies the expression: -(7x - 3y) + 2(x + 4). Her work is shown. In what step does she make a mistake?
likoan [24]

<em><u>Correct steps are shown</u></em>

<em><u>Correct simplified expression is:</u></em>

-(7x - 3y) + 2(x+4) = -5x + 3y+8

<em><u>Solution:</u></em>

<em><u>Given that: Mara simplifies the expression</u></em>

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

<em><u>Correct steps are:</u></em>

From given,

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

<em><u>Use the distributive property,</u></em>

a(b + c) = ab + bc

Therefore,

-(7x - 3y) + 2(x+4) = -7x +3y + 2x + 8

Group the like terms

-(7x - 3y) + 2(x+4) = -7x + 2x + 3y + 8\\\\Combine\ the\ like\ terms\\\\-(7x - 3y) + 2(x+4) = -5x + 3y+8

Thus the expression is simplified
