In the given figure,
Angle 108° + 12x = 180°
because they for pair of co- interior angles which are supplementary.
so,
hence , value of x = 6°
Answer:
f(-3) = -21
Step-by-step explanation:
To find f(-3), we just need to plug x = -3 into f(x) so:
f(-3) = -4 * (-3)² + 15
= -4 * 9 + 15 = -36 + 15 = -21
Answer:
Probably the median since it is 22
Step-by-step explanation:
Answer:
AB = 51
BC = 50
AC = 42
PQ = 42
QR = 42
PR = 59
Step-by-step explanation:
Perimeter of ∆ ABC = Perimeter of ∆ PQR
3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3
9x + 17 = 10x + 3
17 - 3 = 10x - 9x
14 = x
.: x = 14
AB = 3x +9 = 3×14+9 = 42+9 = 51
BC = 3x +8 = 3×14+8 = 42+8 = 50
AC = 3x = 3×14 = 42
PQ = 3x = 3×14 = 42
QR = 3x = 3×14 = 42
PR = 4x +3 = 4×14+3 = 56+3 = 59
Answer:7
Step-by-step explanation:
1,000 meters is equal to 1 kilometer so it would be 7 pretty sure
