Answer:
Step-by-step explanation:
<u>Use the law of cosines to find the side AB:</u>
<u>Use the Heron's area formula next:</u>
, where s- semi perimeter
- s = 1/2[x + x + 3 +
) = 1/2 (2x + 3 + ) - s - a = 1/2 (2x + 3 + - 2x - 6) = 1/2 (
- 3) - s - b = 1/2 (2x + 3 + - 2x) = 1/2 ( + 3)
- s - c = 1/2 (2x + 3 + - 2) = 1/2 (2x + 3 - )
<u>Now</u>
- (s - a)(s - b) = 1/4 [(x²+3x+9) - 9] = 1/4 (x² + 3x)
- s(s - c) = 1/4 [(2x + 3)² - (x² + 3x + 9)] = 1/4 (3x²+ 9x) = 3/4(x² + 3x)
<u>Next</u>
- A² = 3/16(x² + 3x)(x² + 3x)
- 300 = 3/16(x² + 3x)²
- 1600 = (x² + 3x)²
- x² + 3x = 40
<u>Substitute this into the first equation:</u>
Answer:
Very little information is given, leaving room to multiple possible functions, however i would expect it to be y = 4x
Step-by-step explanation:
x * z = y
4 * z = 16
z = 16/4
z = 4
Answer:
A = 36 in.²
Step-by-step explanation:
The area of a parallelogram can be determined by the formula:
A = bh
The base length is 12 inches and the height is 3 inches.
A = 12in. * 3in.
A = 36 in.²

I used my name, lol
Step-by-step explanation:
Kat wants to use her money to support animals at a shelter after receiving her pay check from work . She pays $15 per animal, and leaves $20 for the workers. She can spend at most $130. How many animals can she help?
Solve for x
Add 20 to both sides to isolate x
Divide each side by 15
Kat can help at most 10 animals.
(I am so sorry I took so long, I couldn't come up with anything.)
