I believe the answer is 210 because 1m= 26.25 and that x's 8= 210

the answer is 210  I think

you multiply 105 and 8 and it gets you 840

then you do 840=4x and you divide 840 and 4 and that gets you 210

Find the value of <br> x<br> y, and <br> z in the parallelogram below.
EastWind [94]
Let A be the angle of 79 degrees
B be the angle of (5y-4) degrees
C be the angle of (x+5) degrees
D be the angle of (9z-7) degrees
According to the property of parallelogram
Opposite angles are equal
We get, angle A = angle C
Since angle A = 79 degrees
And angle C = (x+5) degrees
We get, x+5=79
=> x=79-5=74.

Angle B = Angle D
(5y-4)=(9z-7)
Since there’s two variables here, we can’t use the property of “opposite angles are equivalent”
We have to use another property which is adjacent angles are equal
Therefore, we can find angle D
Angle D + Angle A=180
=> 9z-7 =180-79
z=108/9
z=12
Since (5y-4)=(9z-7)
Substitute z=12 in
We get, 5y-4=101
y= 105/5
y= 21
Therefore, x=74, y=21 and z=12.

Add: (3x2 - 5x + 6) + (9 - 8x - 4x2) A) 12x2 - 13x + 2 B) 7x2 + 3x - 3 C) 7x2 - 13x + 15 D) -x2 - 13x + 15
kati45 [8]

Answer:

D

Step-by-step explanation:

So we have the expression:

(3x^2-5x+6)+(9-8x-4x^2)

Combine like terms:

=(3x^2-4x^2)+(-5x-8x)+(6+9)

Add or subtract:

=(-1x^2)+(-13x)+(15)

Simplify:

=-x^2-13x+15

Our answer is D

Find the perimiter now

that is right triangle so
when hpotonouse is c and hthe lgs are a and b
a²+b²=c²

given
leg is 8
hypotonuse is 13

8²+b²=13²
64+b²=169
minus 64 from both sides
b²=105
sqrt both sides
b=√105

find total perimiter
8+13+√105=21+√105

times 1/32 for scale
0.65625+0.32021721143623744947565745876628=
