Answer:
b = 10, c = 9
Step-by-step explanation:
For the triangles to be congruent by the HL postulate, then
UW = DF ( hypotenuse are congruent ), that is
12b - 34 = 5b + 36 ( subtract 5b from both sides )
7b 0 34 = 36 ( add 34 to both sides )
7b = 70 ( divide both sides by 7 )
b = 10
and
UV = EF ( legs are congruent )
4c - 9 = 3c ( subtract 3c from both sides )
c - 9 = 0 ( add 9 to both sides )
c = 9
The sum of the lengths would be the perimeter
Use a calculator to add the values of the sides and you'll have it
Answer:
9,-9
Step-by-step explanation:
Because your opponent is in the positive while you are in the negative
Answer:
hi
Step-by-step explanation:
hi there, i am hooman :)
We will express second equation in first.
y = 3x + 2
after that we get:
3x + 2 = x^2 + 3x - 7
x^2 -9 = 0
x^2 = 9
x1 = 3
x2 = -3
y1 = 3*3+2 = 11
y2 = -3*3 + 2 = -7
we get pairs:
(3,11) and (-3,-7)
Answer is first option.
