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

2. The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers aj set up the variables (2
storchak [24]

Answer:

Larger number = 34

Smaller number = 17

Step-by-step explanation:

Given that:

Sum of numbers = 51

Let,

x be the larger number

y be the smaller number

According to given statement;

x+y=51       Eqn 1

x = 2y        Eqn 2

Putting x=2y in Eqn 1

2y+y=51

3y=51

Dividing both sides by 3

\frac{3y}{3}=\frac{51}{3}\\y=17

Putting y=17 in Eqn 2

x=2(17)

x=34

Hence,

Larger number = 34

Smaller number = 17

What is the slope of a line perpendicular to the line whose equation is x−2y=12.
seraphim [82]

Answer:

-2/x

Step-by-step explanation:

simplified is y = -x/2 - 6

Perpendicular slopes are just reciprocals of the original slope, so just flipp the original slope around to be the complete opposite.

Example if slope= -2, the reciprocal= -1/2

Just flip the numerator with the denominator for perpendicular slope
