Total length of the string Kevin has = 3/4 yard.
He used 1/3 of the total length of the string.
We have total length 3/4 yards.
Therefore,<em> we need to find the 1/3 of 3/4 yards.</em>
1/3 × 3/4
We can see that we have 3 in the bottom of first fraction and 3 on the top of second fraction.
Crossing out 3's we get,
= 1/4 yards.
<h3>Therefore, he used 1/4 yards of string for his project.</h3>
Step-by-step explanation:
5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2
