P1 = 10 m²
P2 = 22 m²
P3 = ?
According to Pythagoras' theorem:
P1 + P2 = P3
P3 = 10 m² + 22 m² = 32 m²
Answer:

Step-by-step explanation:
we know that
To find out how much solution the scientist used for the experiment multiply 3/4 by 1/6
so

simplify

A^2+b^2=c^2
7^2+11^2=?
49+121=170
x= Square root of 170
Hope this helps!! :)
Answer:
a = -1
Step-by-step explanation:
The line of symmetry for the parabola given by ...
y = ax² +bx +c
is
x = -b/(2a)
Using the given values, we have ...
-2 = -(-4)/(2a)
Multiplying by -a/2, we get ...
a = (4/2)(-1/2) = -1
The value of "a" is -1.
