Hello from MrBillDoesMath!
Answer:
104 F = 40 C
Discussion:
9/5C + 32 = F => in our case, F = 104
9/5C + 32 = 104 => subtract 32 from both sides
9/5C = 104 - 32 =>
9/5C = 72 => multiply both sides by 5/9 (the reciprocal of 9/5)
(5/9)*(9/5) C = 72 * (5/9) =>
C = 72*5/9 = 360/9 = 40
Thank you,
MrB
Answer:
x= -6
Step-by-step explanation:
2(x+5)=x+4 (given)
2x+10=x+4 (distribute)
x+10=4 (simplify)
x= -6 (simplify again)
Answer:
Option B.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that triangle ABC is an isosceles triangle.
From the below figure it is clear that the vertices of triangle are A(-2,-4), B(2,-1) and C(3,-4).
Distance formula:

Using this formula, we get



Now,
Perimeter of triangle ABC = AB + BC + AC


So, perimeter of triangle ABC is
units.
Therefore, the correct option is B.
