Answer:
x = -8
Step-by-step explanation:
9/4 = (x-10)/x
Cross multiplying,
9x = 4(x - 10)
9x = 4x - 40
9x - 4x = -40
5x = -40
x = -40/5
x = -8

If DE = 10 in. and GH = 4 in., what is the length of the radius? Round to the nearest tenth. A 5.4 in. B 6.4 in. C 10.8 in. D 29.0 in.
Answer:
A. 5.4 in
Step-by-step explanation:
At the top of the line segment GH, you can see it ends on Circle D's circumference. Therefore, if you made a line segment from D to G, its length would be the radius. Lines DE and GH are perpendicular and make a 90 degree angle, so you can make line DG a hypotenuse, use pythagoreans theorem, and find the radius. However, since they intersect at a halfway point, you have to divide 10 and 4 by 2. 10/2 = 5 4/2 = 2 5^2 + 2^2 = r^2
5^2 = 25 and 2^2 = 4, so 29 = r^2. The square root of 29 is 5.385, or 5.4 inches.

Expression equivalent to a^2-144b^2
Answer:
(a - 12b)(a + 12b).
Step-by-step explanation:
a^2 - 144b^2
This is the difference of 2 squares identity:
a^2 - b^2 = (a - b)(a + b)
So for the given expression we have:
(a - 12b)(a + 12b).
- (as a is square root of a^2 and 12b is the square root of 144b^2.).

Answer:
3. P = 48 units A = 116 units²
Step-by-step explanation:
A = 12 x 12
= 144
Now we can subtract the missing areas. 4 x 4 = 16 and 6 x 2 = 12.
144 - 16 - 12
= 116 units²
P = 12 + 12 + 12 + 12
= 48 units

The ratio of the sides of a triangle is 2:5:3. If the perimeter of the triangle is 190 meters, what is the length of the longest side
Answer:
Step-by-step explanation:
Remark
Let x by the multiplying factor to make up 190 m.
2x + 5x + 3x = 190
10x = 190
x = 190/10
x = 19
The longest side is 5x
The longest side = 5 * 19 = 95

Answer:
x=2
Step-by-step explanation:
Combine like terms, add 8 to both sides of the equation, simplify, divide both sides by the same term, simplify
Answer:
x = 2
Step-by-step explanation:
1. Combine like terms
15x - 8 - 3x = 16
1 2 − 8 = 1 6
2. Add 8 to both sides of the equation
1 2 − 8 = 1 6
+8 +8
3. Simplify
12x = 24
12x/12 = 24/12
x = 2
The length of a rectangle is two times
its width. If the perimeter of the
rectangle is 150 in, what is the length of
the rectangle?
Answer:
length=50
width=25
step-by-step explanation:
=length=2x
=width=x
=perimeter 2(l+b)
=2(2x+x)×150
=2x+x=150÷2
=2x+x=75
=3x=75
=x=75÷3
=25
=length=25×2=50
=width=25

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2
Answer:
-11/10 (fraction) or -1.1 (decimal)
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
x1 = 7
x2 = -3
y1 = -7
y2 = 4
So, it’s: (4 - (-7))/(-3-7)
= (4+7)/(-3-7)
= (11)/(-10)
= -11/10 or -1.1

Answer:
Prism A: 264; Prism B: 265.125
Step-by-step explanation:
✔️Surface area of the triangular prism = base area + Perimeter*Height of prism
Base area = ½*bh
b = 6 cm
h = 8 cm
Base area = ½*6*8 = 24 cm²
Perimeter of base = 6 + 8 + 10 = 24 cm
Height of prism = 10 cm
Surface area of the triangular prism = 24 + 24*10 = 264 cm²
✔️Surface area of rectangular prism = 2(LW + LH + HW)
L = 5.25 cm
W = 5.25 cm
H = 10 cm
Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)
= 265.125
