Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{(x + 4) and (x - 1)}}}}}$

Step-by-step explanation:

$\sf{ {x}^{2} + 3x - 4}$

Find the two numbers that multiplies to 4 and subtracts to 3. The numbers are 4 and 1

$\dashrightarrow{ \sf{ {x}^{2} + (4 - 1)x - 4}}$

$\dashrightarrow{ \sf{ {x}^{2} + 4x - x - 4}}$

Take x as common

$\dashrightarrow{ \sf{x(x + 4) -x - 4}}$

Take 1 as common

$\dashrightarrow{ \sf{x(x + 4) - 1(x + 4)}}$

$\dashrightarrow{ \sf{(x + 4)(x - 1)}}$

Hope I helped!

Best regards! :D

⦁ Show (2.3)(5.06) as a fraction multiplication problem and explain why the answer is in thousandths (three decimal places).

astra-53 [7]

we have

$(2.3)(5.06)$

we know that

$2.3=\frac{23}{10}$

$5.06=\frac{506}{100}$

$(2.3)(5.06)=(\frac{23}{10})(\frac{506}{100})$

$=\frac{11,638}{1,000}$

$=11.638$

the answer is in thousandths, because the denominator of the multiplication of the two fractions is one thousand

4+4+4+4

8+8+8+8

(-1)(4+4+4+4)

(-8) + (-8) + (-8) + (-8)

Answer:

$Total = (-8) +(-8) +(-8) +(-8)$
