Answer:
x = 24
Step-by-step explanation:
Since this is a right angle, we can use the Pythagorean Theorem to find x. In the formula, a^2 + b^2 = c^2, variables a and b represent the lengths of the legs, and variable c represents the length of the hypotenuse.
a^2 + b^2 = c^2
18^2 + x^2 = 30^2
324 + x^2 = 900
x^2 = 576
x = 24
<h2>Answer: </h2>
1. <u>Area = b × h</u>
A = 5 × 3
A = 15cm².
2. <u>Area = ½(a + b) × h</u>
A = ½(9 + 15) × 15
A = ½ × 24 × 15
A = 12 × 15
A = 180mm².
3. <u>Area = 2(l × b) + l × b</u>
A = 2(12 × 4) + 6 × 3
A = 2 × 48 + 18
A = 96 + 18
A = 114m².
We may have this planned like this:
two years is 8 quarters
<span>Assuming simple interest, </span>
You will use the formula
<span>A = P(1+rt) </span>
<span>= 400(1+8*.03) </span>
<span>= 496
</span>I think this is the answer:) Hope it helps a lot
