It is 19 because 53 I know I was guessing Bc Idk Im annoying
Answer:
False
Step-by-step explanation:
4 cos^4 (4x)-3 = 0
Substitute into the equation
4 cos^4 (4pi/24)-3 = 0
4 cos^4 (pi/6)-3 = 0
Take the cos pi/6
4 ( sqrt(3)/2) ^4 -3 =0
Take it to the 4th power
4 ( 9/16) -3 =0
9/4 -3 =0
9/4 - 12/4 = 0
-3/4 =0
False
Answer:
10²
Step-by-step explanation:
left triangle = 2 × 2 = 4 ÷ 2 = 2²
right triangle = 2 × 4 = 8 8 ÷ 2 = 4²
middle square = 2 × 2 = 4²
2 + 4 + 4 = 10²
You must have an illustration to give an idea what x represents. If not, then we can never find a way to answer this for you. However, for educational purposes, let me just suppose a figure for us to solve. The diagram is shown in the attached picture.
The rectangle has dimensions of 6 + x by x units, where x is the width and (6+x) is the length. If you are given the perimeter of the rectangle, then the working equation to be used is shown below.
Perimeter = 2L + 2W
Generally, perimeter is the sum of all sides of the figure. Since rectangle is defined to be made up of two sets of equal parallel sides called length and width, the perimeter is simplified to be that way. Substituting the values,
96 inches = 2(6+x) + 2x
96 = 12 + 2x + 2x
96 = 12 + 4x
4x = 96 - 12
4x = 84
x = 84/4
x = 21 inches
Answer:
-12
Step-by-step explanation:
−2.5+(−7.4)−(−1.2)−(+3.9)+(+0.6)
Subtracting a negative is adding
−2.5+(−7.4)+(1.2)−(+3.9)+(+0.6)
Combine like terms
-9.9 +(1.2)−(+3.9)+(+0.6)
-8.7-3.9+.6
-12.6+.6
-12
