5t + (t - 3) - [(7t + 5) - (8 - 3t)] (multiply -1 to (8 - 3t)
5t + (t - 3) - [(7t + 5) - 8 + 3t]
5t + (t - 3) - [7t + 3t + 5 - 8]
5t + (t - 3) - [10t - 3] (multiply -1 to [10t - 3]
5t + (t - 3) - 10t + 3
5t + t - 10t - 3 + 3
-4t

Answer:
Step-by-step explanation:
We can add a line to create a triangle and a rectangle. The triangle will have side lengths 10 and 6. Furthermore, it will be a right triangle, meaning we can apply the Pythagorean Theorem to find x, the hypotenuse.

Answer:
c) x = 20, angle COD = 70 °
Step-by-step explanation:
(x+50)° + 90° +20° = 180°
x + 160° = 180°
x = 180°- 160°
x = 20
Angle COD = (x+50)° = (20 +50)° = 70°

The length of the band in terms of π is given by the expression:
L = 40mm + π*10mm
<h3>
How to get the length of the band?</h3>
Remember that for a circle of diameter D, the circumference is:
C = π*D.
Now, if you look at the image, you can see that the length of the band will be equal to 4 times the diameter of the pencils (one time for each side). Plus 4 times one-fourth of the circumference of each pencil (for the four corners).
because the diameter is 10mm, the length of the band will be:
L = 4*10mm + 4*(π*10mm/4)
L = 40mm + π*10mm
This is the length of the band in terms of π.

<span>7 x 7 = 49 area of square.</span>
<span /><span> The radius of the circle is half the diameter. 7 cm/2 = 3.5 </span>
<span> A = 3.14 × 3.5 cm × 3.5 cm = 38.465</span>
Finale step. Subtract the area of the circle from the area of the square.
49 cm^2 −38.465 cm^2 = 10.535 or round to 10.54 cm^2
D. 10.54
