Easy to find out...
y = 3x - 17
(2,-11)....x = 2 and y = -11
now we sub
-11 = 3(2) - 17
-11 = 6 - 17
-11 = -11...correct....so it IS a solution
3n+4<-62
n being the number
+4 for the number being increased by 4.
3n=3*n
< the less than sign
Hope this helped!
Answer:
Length: 23.38
Width: 3.34
Step-by-step explanation:
First I drew out a diagram so that I could visibly see the problem. [ a rectangle with 7x on one side and x on the other.
So to find the area you multiply length time width and 7x times x is 7x^2. The actual area is given: 78, so you set that equal to 7x^2.
Then you want to divide by 7 to get 11.14. Then you want to take the square root of 11.14 to get 3.338 which rounds to 3.34 {try not to round until the very end]. This gives you the width of the rectangle, so to find the length you would have to multiply x by 7 to get 23.38. When you multiply the length and width (3.34 x 23.38) you get 78.08 which can round to 78.
7x^2 = 78
x^2 = 78/7
x^2= 11.142...
x = sqrt(1.142...)
x = 3.338 --> 3.34 --> width
3.34 x 7 --> 23.38 --> length
3.34 x 23.38 --> 70.8

<h2>Step-by-step explanation:</h2>
<u>By using external angle property</u>,
- x + x = x + 46
- 2x = x + 46
- 2x - x = 46
- x = 46 <u>Ans.</u>
Note : External angle property theorem is used when <u>sum of other two internal angle is equal to external angle</u>.
15 the answer is 15 because 15 x 5 = 75
