What is the expression in factored form? x^2+13x+42 answer with steps/process for answer!

The answer is (x+6)(x+7)

Note that  ( x − a ) ( x − b ) = x 2 − ( a + b ) x + ( a × b )

Also note that  13 = 6 + 7  and  42 = 6 × 7

So  x 2 − 13 x + 42 = ( x − 6 ) ( x − 7 )

                                                hope it helps

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
