Answer:
<u><em>x=9</em></u>.
<em><u>perimeter=68</u></em>
<em><u>area=168</u></em>
Step-by-step explanation:
First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to multiply the length and the width so 28x6 which is <em><u>168</u></em>.
hope that helped :)
Answer:
The missing number would be 17
Step-by-step explanation:
Answer:
5/12 > 3/8
Step-by-step explanation:
to see which is bigger, find the LCD of both fractions and whichever has the biggest numerator is the larger fraction.
the LCD of 5/12 and 3/8 is 24.
to get a denominator of 24 for 5/12 we would multiply the fraction by 2, which gives us 10/24
to get a denominator of 24 for 3/8 we would multiply the fraction by 3, which gives us 9/24.
10/24 > 9/24
looking back at the original fractions, 5/12 is the largest fraction
A = 7 and x = -5
-a + 3x = -(7) + 3(-5) = -7 -15 = -22
Answer: -22
Answer:
The equation of the line would be y = 4/9x
Step-by-step explanation:
In order to find the equation, we first need to find the slope. We can do this by using the slope equation with the points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (9 - 0)/(4 - 0)
m = 9/4
Now that we have this, we can use point-slope form along with one of the points to get the equation.
y - y1 = m(x -x1)
y - 0 = 4/9(x - 0)
y = 4/9x
