Answer:
$1.21
Step-by-step explanation:
1.42 x 0.85
1.207
Because taking an absolute value of a number means making positive, then we can conclude that the absolute value of both numbers are 8.
|-8| = 8
|8| = 8
Answer: The first one is not a function the second is a function the third one is not one and the fourth one is
Step-by-step explanation:
Neither P, nor A are on the sketch
I guess P is the upper right corner of the rectangle
and A=(0,1)
P belongs to the line going through (1,0) and B(0,y)
<span>but we don't know the y-coordinate of B </span>
<span>the triangle is right and isosceles, so pythagoras a²+a²=2² ... 2a²=4 ... a²=2 ... a=sqrt2 </span>
now look at the right triangle BOA
<span>his hypotenuse is AB=sqrt2 and the <span>the kathete</span> OA is 1 </span>
so y²+1²=(sqrt2)² ... y²+1=2 ... y²=1.. y=1
so the coordinates of B are (0,1)
the line going through (1,0) and (0,1) is L(x)=-x+1
P belongs to this line, so the coordinates of P are P(x,-x+1) (0<x<1)
b) so if that's P, the height of the rectangle is -x+1 and the width=2x
<span>so its area A(x)=2x*(-x+1)= -2x²+2x
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:
A; C; 35; A; A,B,D
Step-by-step explanation:
1. GH = sqrt(4^2 + 6^2) = sqrt(52) = 2sqrt(13)
FG = sqrt (9^2 + 4^2) = sqrt97
Add them together, and multiply by 2 to get the perimeter (because JH = GH, and FG = FJ). You get A (4sqrt13 + 2sqrt97)
2. C, because that is basically saying that all the angles are right
3. The lines are equally spaced (horizontally), and parallel, making them increase by the same amount between each. This means that (8x-7) - (7x+2) = (7x+2) - (10x-1).
Simplify:
x-9 = -3x+3 -->
4x = 12,
x =3
This means that the parallel lines' lengths are 17, 23, 29. This means that they increase by 6. This makes the longest base 29 + 6 = 35
4. The sum of exterior angles is ALWAYS 360. Divide 360 by 18 to find out how many sides it has. 360/18 = 20. The answer is A.
