(x+4)(x+25)

Step-by-step explanation:

x*x=x^2

x*20=20x

4*x=4x

4*25=100

x^2+20x+4x+100

put the commons together and you will get

x^2+29x+100

Papessa [141]

Answer: 60 hours.

Step-by-step explanation:

Let be "x" the amount of hours Nick practice in March and "y" the amount of hours Nick plans to practice in April.

Set up a system of equations:

$\left \{ {{x=42} \atop {y=x+18}} \right.$

Applying the Substitution Method, we can substitute the first equation into the second equation in order to find the value of "y". Therefore you get this result:

$y=x+18\\\\y=(42)+18\\\\y=60$

Find the slope-intercept form of the line whose slope is 5 and that passes through the point left (-2,8)

Doss [256]

$\text{The slope-intercept form:}\ y=mx+b\\\\\text{m-a slope; b-a y-intercept}$

$\text{We have:}\\m=5\\\text{therefore}\ y=5x+b$

$\text{We know, the line passes through the point}\ (-2;\ 8)\to x=-2;\ y=8\\\\\text{substitute the values of x and y to the equation of the line:}\\\\8=5(-2)+b\\\\8=-10+b\ \ \ |+10\\\\b=18$

$\text{Your answer:}\ y=5x+18$
