Answer:
nno
Step-by-step explanation:
You can solve this 2 ways: plug in all of the options or solve for x.
i going to solve for x.
given: x^2+2x=24 (subtract 24 on both sides to get make it look like x^2+x+1)
x^2+2x-24=0 (now factor x^2+2x-24 out)
<span>x^2+2x-24 --> (x-4)(x+6)
</span>
new equation: <span>(x-4)(x+6)=0 (now make them both equl zero)
new equaions: </span>x-4=0 x+6=0 <span> (now solve for x for both)
x-4=0 x+6=0
x=4 x=-6
your <span>answer is 4 and -6.
if you were not taught how to do what i just did then i can message you how to plug those numbers into </span></span><span> x^2+2x=24 to find the answer.</span>
Answer:
The ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1
Step-by-step explanation:
The diameter of a larger circle = d = 40 cm
r = d/2 = 40/2 = 20 cm
The area of the larger circle = πr²
= 3.14 (20)²
= 3.14 × 400
= 1256 cm²
The diameter of a smaller circle = 20 cm
r = d/2 = 20/2 = 10 cm
The area of the smaller circle = πr²
= 3.14 (10)²
= 3.14 × 100
= 314 cm²
Thus,
The area of the larger circle = 1256 cm²
The area of the smaller circle = 314 cm²
Therefore,
The ratio of the area of the larger circle to the area of the smaller circle will be computed as:
reducing the ration into a simpler form
Thus, the ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1
Answer:
Correct answer is <em>A) Complements of the same angle are congruent.</em>
Step-by-step explanation:
According to Congruent Complement Theorem,
<em><u>"
If 2 angles are complementary to the same angle, then they are congruent to each other".</u></em>
Here, ∠CEF is complementary to ∠DCF, hence ∠DCF ≅ ∠FEG.
Answer:
20
Step-by-step explanation:
It is because 9x2=18
3 subtracted from 18 is 15
15+5=20
