Complete the math in the brackets (4a + 1)
Multiple each term in the brackets by 4a
4a (8a - 4a + 1)
4a (4a + 1)
16a^2 + 4a
Answer:
$1.25
Step-by-step explanation:
2 × $1 = $2
4 × 1 = 4
1 × 1 = 10
$2 + 4 + 10
$2.14
$2.14 - $0.89
$1.25
The answer is 75 I asked Siri
Answer:
The circumference is 37.68 ft.
Step-by-step explanation:
6 * 2 = 12
d = 12
C =
d
C = 3.14 * 12
C = 37.68
We know that
angle (3x) and angle (9x) are supplementary angles
so
3x+9x=180°------> 12x=180°------> x=180°/12-----> x=15°
angle (9x) and angle (1) are supplementary angles
so
9x+∡1=180---------> 9*15+∡1=180
∡1=180-9*15---------> ∡1=180-135------> ∡1=45°
the answer is
∡1 is 45°
alternative method
angle 1 = angle 3x----------> vertical angles
∡1=3x-----> 3*15-----> 45°
