Im assuming its x^2+4x+3.....for x squared right.
First get the product of two numbers that equal to 3 (+3 * +1)
But also add up to 4 (+3 + <span>+1</span>)
so you apply them to your x^2
(x+3)(x+1)
3 hours and 20 minutes minus 1 hour and 48 minuets equals an hour and 32 minutes. There are 60 minuets in an hour and 60 divided by 32 is 0.53. This means that your final answer is:
D. 1.53
All the real forth roots of
is <span>±5</span>
<span>We all know that the interior angles of a triangle sums up to 180</span>°. To get the missing angle, we simply subtract the sum of the given angles from 180°
<span>
Similar triangles have the same measure of angles.
Triangle 1: 80°, 62° </span>→ 180 - 80 - 62 = 38°<span>
Triangle 2: 62°, 38° </span>→ 180 - 62 - 38 = 80° SIMILAR TRIANGLES<span>
Triangle 1: 29°, 47° </span>→ 180 - 29 - 47 = 104°<span>
Triangle 2: 91°, 76° </span>→ 180 - 91 - 76 = 13° NOT SIMILAR<span>
Triangle 1: 100°, 45° </span>→ 180 - 100 - 45 = 35°<span>
Triangle 2: 25°, 45° </span>→ 180 - 25 - 45 = 110° NOT SIMILAR
Q4) x+4 = 15
15-4 = x
x = 11
Q5)
18 + 12 = x
x - 12 = 18
30 - 12 = 18
x = 30
I hope this helped, please give this the Brainliest answer! :3
