Answer:
<h3>27 cm²</h3>
Step-by-step explanation:
The length is 3 × width.
l = 3w
The perimeter is 24 centimeters.
P = 2l + 2w
24 = 2(3w) + 2w
24 = 6w + 2w
24 = 8w
3 = w
The width is 3 centimeters.
l = 3(3)
l = 9
The length is 9 centimeters.
Area is l × w.
A = l × w
A = 9 × 3
A = 27
The area is 27 squared centimeters.
Your answer is A because the other ones are to small to measure

Step-by-step explanation:
<h3>Given function </h3>
<u>Another notation for same function is</u>
- y = 5x - 7, where 5 is the slope and -7 is the y-intercept
<h3>Questions
</h3>
<u>1. Is the function increasing or decreasing?
</u>
- Increasing as x has positive slope
<u>2. What is the y-intercept?
</u>
<u>3. What is the slope?
</u>
<u>4. What is f(-2)?
</u>
- f(-2) = 5(-2) - 7 = - 10 - 7 = -17
<u>5. If f(x) = 0, what is x?</u>
- f(x) = 0
- 0 = 5x - 7
- 5x = 7
- x = 7/5
- x = 1.4
Answer:
100(x) /÷0p1
Step-by-step explanation:
t(x) factor 4
2x2 + 5xy - 3y
there are three terms in the simplified expression
there is one negative term in the simplified expression
