This question can’t be answered without the original coordinates of ABC
Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer:
1. f (2) = 3 x 2^x-1
2. f (-1) = -3 x 2^x
3. f (10) = 3 x 2^x/10

Answer:
63 m^2
Step-by-step explanation:
The figure appears to be a parallelogram.
area of parallelogram = base * height
Use the 14-m side as the base. Then the height is the perpendicular distance between the two opposite 14-m sides, so the height is 4.5 m.
area = base * height
area = 14 m * 4.5 m
area = 63 m^2
P.S. The choices are given in square meters (m^2), which is a unit of area, not in meter times square root of 2 "m sqrt(2)."
Answer:
x = -4 ±3
x = -7,-1
Step-by-step explanation:
x^2 + 8x = -7
1/2 B ^ 2 = 16
x^2 + 8x + 16 = 16 -7
(x + 4) ^2 = 9
x + 4 = ±3
x = -4 ±3
x = -7,-1
