Answer:

-1a^3+2a^2-4a+3

Step-by-step explanation:

Subtract:6a^3 - 2a^2 + 4 from 5a^3 - 4a + 7

(5a^3-4a+7)-(6a^3-2a^2+4)

To subtract multiply the negative sign inside the parenthesis and combine like terms

5a^3-4a+7-6a^3+2a^2-4

Combine the like terms

5a^3-6a^3= -1a^3, 7-4=3

No like terms for -2a^2 and 4a. so it remains the same

5a^3-4a+7-6a^3+2a^2-4

-1a^3+2a^2-4a+3

Is anyone good with this? I need help finding the answer.

To solve this problem, we have to find the perimeter of the shape.
we already know that two of the sides are 82m, all we need to do is find the circumference of the semicircles.
to find circumference, you multiply the diameter of a circle by pi. since we have two identical semicircles, we have one full circle. 66•3.14=207.24
207.24+82+82=371.24
the answer is 371.24m

Pythagorean Theorem: a^2 + b^2 = c^2

-A and B are legs of the triangle

-C is the hypotenuse

#1.

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

c = 10

#2.

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

c = 13

#4.

10^2 + 4^2 = c^2

100 + 16 = c^2

116 = c^2

c = 4\sqrt{29}

#5.

15^2 + 9^2 = c^2

225 + 81 = c^2

306 = c^2

c = 3\sqrt{34}

#6.

120^2 + b^2 = 150^2

14400 + b^2 = 22500

b^2 = 8100

b = 90

#7.

144^2 + b^2 = 194^2

20736 + b^2 = 37636

b^2 = 16900

b = 130

Hope this helps!! :)
