Answer:
0.004, 4%, 1/4, 4/9.
Explanation:
Area of a circle using the radius is pi*r^2, so:
A=3.14*4^2
A=3.14*16
A=50.24
Answer 32
Step-by-step explanation
32, Give Me Brainiest Please.
Answer:
(15x-2)°+( 7x+4)°=90° --> 15x-2°+7x+4°=90° --> 22x+2°=90° --> 22x=90°-2° --> 22x=88° --> x=88/22 --> x=4.
m/_BAC=(15x-2)°=15×4-2 =58°
m/_CAD=(7x+4)°=7×4+4= 32°.
X^2-4 = x^2 - 2^2
= (x+2)(x-2)
