Answer:
here's one l times height idk the other two lol
Step-by-step explanation:sorry
Answer:
Step-by-step explanation:
Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that
(x+2)+(x+2)+(2x+3)+(2x+3)=46
Combine like terms to get: 6x+10=46
Subtract 10 from both sides to get: 6x=36
Divide both sides by 6 to get: x=6.
The answer is 376.8 m.
It is given:
radius: r = 60 m
<span>π = 3.14
c = </span><span>π * d
d - diameter.
It is known that diameter is twice of radius:
d = 2r
So, implement it in the formula:
c = </span>π * d = π * 2r = 3.14 * 2 * 60 = 376.8 m

Answer: C) ASA Theorem</h3>
================================================
Explanation:
Let's go through the answer choices one at a time.
- A) The AA postulate is only used for similar triangles, and not congruent triangles. We need information about at least one pair of sides. Using the angles only isn't enough. We can rule out choice A.
- B) The HL postulate only applies to right triangles. These triangles are acute triangles, so we can rule out choice B.
- C) This is the answer as we can rule out choice D, so this is the only thing left. Also, if we know that angle A = angle A'' and angle B = angle B'', then we could use the ASA theorem to prove the triangles congruent.
- D) This is not a valid congruence theorem. This is because we could have ambiguous cases that arise and lead to confusion. Also, it is possible that if we know two sides and a non-included angle, then a triangle may not be able to be formed. It will depend on the angle and side values. Therefore, we can rule out choice D.
To find both f(8) and f(-5), we will need to plug in their values for x and solve for each. Then, we can subtract them to find the final answer.
Finding f(8):
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
Finding f(-5):
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
Subtracting f(8) and f(-5):
f(8) - f(-5)
22 - - 17
22 + 17
39
Hope this helps!! :)
