Answer:
20
Step-by-step explanation:
first find the are of the entire rectangle
6×4= 24
then find the one of the white one
2×2= 4
subtract the 4 from 24
24-4=20
Answer:
26 sq in.
Step-by-step explanation:
Let x = measure of one acute angle
3x - 2 = measure of other acute angle
Since the triangle is a right triangle, the sum of the measures of the acute angles is 90
x + 3x - 2 = 90
4x - 2 = 90
4x = 92
x = 23
90 - 23 = 67
The acute angles are 23° and 67°
Now, let a = length of side opposite the 23° angle
sin 23 = a/12
a = 12 sin 23
Let b = length of the side opposite the 67° angle
sin 67 = b/12
b = 12 sin 67
Area = 1/2ab = 1/2(12 sin 23°)(12 sin 67°)
= 25.90
26 sq in to the nearest inch
Wow! That is quite the problem.
Answer:
No, the opposite would be negative 6/4
Step-by-step explanation:
3/2 is just a simplified version of 6/4
Answer:
the third option, x = –3, –1, 3
Step-by-step explanation:
Answer:
The standard for would be y = -3x^2 - 24x - 46
Step-by-step explanation:
To get this to standard form, start by squaring the parenthesis.
y - 2 = -3(x + 4)^2
y - 2 = -3(x^2 + 8x + 16)
Now distribute the -3
y - 2 = -3x^2 - 24x - 48
Now add the 2 to both sides
y = -3x^2 - 24x - 46
