shadow
5×3=15
4x3=12 so the birdhouse and pole are 12
feet
THANKS!
Answer:
Step-by-step explanation:
2x2+5x−10=x2+4
Step 1: Subtract x^2+4 from both sides.
2x2+5x−10−(x2+4)=x2+4−(x2+4)
x2+5x−14=0
For this equation: a=1, b=5, c=-14
1x2+5x+−14=0
Step 2: Use quadratic formula with a=1, b=5, c=-14.
x=
−b±√b2−4ac
2a
x=
−(5)±√(5)2−4(1)(−14)
2(1)
x=
−5±√81

x=2 or x=−7
Answer:
x=2 or x=−7
Answer:
n + p = m
Step-by-step explanation:
x(the unnamed angle) and m both equal 180
x + m = 180
x + n + p =180
180 = 180
x + m = x + n + p
m = n + p
Answer:
Step-by-step explanation:
Answer: y = -1x + 8
Step-by-step explanation: linear equations must be written in the format
y = mx + b from.
m represents the slope which it -1
b represents the y-intercept which is 8.
Just substitute the slope and y-intercept in the m and b places and that is a linear equation.
