Answer:
x = 3Step-by-step explanation:
Based on similar triangle;
14/49 = x+5/9x+1
Cross multiply
49(x+5) = 14(9x+1)
49x + 245 = 126x + 14
49x - 126x = 14 - 245
-77x = -231
x = -231/-77
x = 3
Hence the value of x is 3

Step-by-step explanation:
What Julie did wrong was, she did simplify she just did it wrong. She used 4*8 which does equal 32 but 8 can't be simplified anymore than that. If she would of used 2*16 then her answer would be right.
Hope this helps!
Answer:
[tex]5 \sqrt{18} - \sqrt{32} \\ = 5 \sqrt{9 \times 2} - \sqrt{4 \times 4 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }[/tex]

Suzanne is putting a fence around her rectangular garden. The length of the garden, x, is 4 feet more than the width. The perimeter of the garden is 32 feet. Write an equation to find the length of the garden.
Enter the correct answer in the box.
Answer:
Length=10 feet
Width=6 feet
Step-by-step explanation:
Let width (W) of the garden is x feet
Then Length=L=4+x feet
Perimeter=P=2(W + L)
P=2(x+x+4)
32=4x+8
4x=32-8
x=24/4=6 feet
W=6 feet
L=10 feet

2) Solve each problem with right angle at C:.
a) Find all sides and angles when B = 67º and c=16.
b) Find all sides and angles when b= 2 and c=6
Answer:
Step-by-step explanation:
a.)
<A = 90 - 67 = 23* A = (a^2 + 14.72^2 = 16^2) = a = 6.25
<B = 67* B = (sin67 = b/16) = sin67*16 = 14.73
<C = 90* C = 16
b.)
a = (a^2 + 2^2 = 6^2) = a = 5. 66 <A = (cosA = 2/6) = 70.53*
b = 2 <B = 90-70.53 = 19.47*
c = 6 <C = 90*
How do you solve -2+x=-x+2
Answer:
x=2
Step-by-step explanation:
-2 + x = -x + 2
Isolate the variable
2x = 4
Simplify
x = 2
Answer:
x = 2
Step-by-step explanation:
you want to move the variables to one side, the numbers to the other side.
x = -x+4
then you move the other x
2x = 4
x = 2

Determine the coordinates of the midpoint of the line
segment with endpoints R(6,-2) and S(-3,-2).
O (1,2)
O (1.5, 2)
O (1.5, -2)
(3,-2)
Answer:
(1.5, -2)
Step-by-step explanation:
First subract -3 from 6 to find the total distance of the line segment.
6 - (-3)
Two negatives make a positive
6 + 3
9 units distance
Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.
-3 + 4.5
-3 + 3 + 1.5
(1.5, -2)
6 - 4.5
6 - 4 - 0.5
2 - 0.5
(1.5, -2)
The midpoint of segment RS is (1.5, -2).

HELP ME I BEG U a solution to the equation 4x-3y=12 must also be a solution to which of the following equation?
(1) 4x+3y= -12
(2) 12x-9y=36
(3) 2x-3y=6
(4) 8x-6y=12
Answer:
(2) is the correct answer
Step-by-step explanation:
if you multiply the given equation by 3 you get answer (2):
3(4x - 3y) = 3(12)
12x - 9y = 36
Answer:
(2) 12x-9y=36
Step-by-step explanation:
4x-3y=12 (×3)
12x-9y=36

a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. write an expression that represents all possible widths (use the variable x) of the rectangle. write your answer as an inequality, a < x < b.
Answer: -6<x<5
Step-by-step explanation:
Given
Length is 3 m more than three times the width
Suppose width is x
So, the length is 3x+3
The area of a rectangle is [tex]length\times width[/tex]
Area= [tex](3x+3)x<90[/tex]
[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]

Find the slope of the line passing through the points (-5,6) and (6,6).
slope:
Answer:
0
Step-by-step explanation:
the equation on finding slope is y2 - y1/x2 - x1
so it is...
6 - 6 = 0
6 - -5 = 11
0/11 but that doesnt work so I believe the slope is zero because the denominator is not the one being a 0
hope I helped ;)
Answer: its a zero slope

Using the figure above, what are the measures of the 3 angles in triangle DEF? PLS HURRY! THANKS
Answer:
F= 34 degrees (alternate angles are equal)
To find D
we first have to find the angles at AB
B =180- 165 (sum of angles on a straight line = 180°)
therefore B = 15°(we'll use this to find the angle at E)
A=34 (from the diagram)
so,
D = 180- (15 + 34) [sum of angles in a triangle = 180°]
D = 131°
E=15° (alternate angles are equal )
Step-by-step explanation:
there u go!
