=6x+20
Step-by-step explanation:
3(x+5)+(3x+5)
Solution:
=3x+15+3x+5
=6x+20
Answer:
all real numbers
Step-by-step explanation:
Slope-intercept form:
y = m x + b
7 x - y = - 3
- y = - 7 x - 3 / * ( - 1 )( we have to multiply both sides of the equation by - 1 )
Answer:
y = 7 x + 3
You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):

We have to solve for h:


You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is
B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
