Factor:<br><br><br>(m+2)^2−(m+2)+mn·(n+2)+2n(n+2)

bazaltina [42]

ANSWER
${(m + 2)}( {n}^{2} + 2n + m + 1)$

EXPLANATION

The given expression is

${(m + 2)}^{2} - (m + 2) + mn(n + 2) + 2n(n + 2)$

We factor to get,

$= {(m + 2)}(m + 2 - 1) +n (n + 2) (m+ 2)$

This implies that,

$= {(m + 2)}(m + 1) +n (n + 2) (m+ 2)$

We factor further to obtain,

$= {(m + 2)}((m + 1) +n (n + 2))$

or

$= {(m + 2)}( {n}^{2} + 2n + m + 1)$

I don’t understand this problem and need help!

butalik [34]

Answer:

see explanation

Step-by-step explanation:

Since AB and BC are perpendicular, then

∠ABC = 90° and

∠ABD + ∠DBC = ∠ABC ← substitute values

3r + 5 + 5r - 27 = 90, that is

8r - 22 = 90 ( add 22 to both sides )

8r = 112 ( divide both sides by 8 )

r = 14

Hence

∠ABD = 3r + 5 = (3 × 14) + 5 = 42 + 5 = 47°

∠DBC = 5r - 27 = (5 × 14) - 27 = 70 - 27 = 43°
