i think its 12 because the two triangles look identical so both angles should measure up to 60°. 5 × 12 = 60. also in that case y would be 7.
Answer:
kenzie can only buy 2 sets of scrunchies unless she can buy half then it would be 2.5.
Step-by-step explanation:
20 scrunchies = $3.00 meaning= $3.00+$3.00 = 6 dollars. Anymore would be over the limit of money she would be able to use for the scrunchies.
P= (2)(x-2)+(2)(5)
P= (x-2)+(x-2)+5+5
Area of rectangle = length × width
300 = (x+10) × x
300 = 10x + x^2
Now we have the equation y=x^2 + 10x - 300
We can factor this equation to get our zeroes, which are:
-5(1+sqrt(13)),
5(sqrt(13)-1)
We only use the positive zero because we can't have a negative dimension.
Your width would be:
5(sqrt(13)-1)
Your length would be:
5(sqrt(13)-1) + 10
