Answer:
x = 6
Step-by-step explanation:
Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is
= 
( cross- multiply )
x(x - 4) = 12 ← distribute left side
x² - 4x = 12 ( subtract 12 from both sides )
x² - 4x - 12 = 0 ← in standard form
(x - 6)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 2 = 0 ⇒ x = - 2
However, x > 0 , thus x = 6
The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
Answer:
The amount of interest Coach Cliffman earned after 3 years is $108.
Step-by-step explanation:
The equation for simple interest is A = P(1 + rt). To determine the revenue earned, subtract the principal amount ($1800) from the total accured amount (principal + interest). The equation for simple interest is A = P(1 + rt), <em>P </em>meaning principal interest, <em>r</em> being the rate of interest per year in decimal form, and <em>t</em> as time in years.
Let P = $1800, r = .02, and t = 3 and you'll end up with a total accrued amount of $1908. Finally, subtract 1908-1800 to get your answer of $108.
Area of a square =a^2
40000=a^2
a=200 inch
Now if u can imagine a square shape with side of 200 inch each.it makes right angles
so use pythagorean theorm
c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch
ength of a fence is 282.84 inch
Answer:
The correct options are:
- cubic decimeter and liter
- cubic centimeter and milliliter
Step-by-step explanation:
1) The 1 cubic decimeter is equal to the 1 liter.
2) The 1 cubic centimeter is equal to the 1 milliliter.
3) Since,1 cubic decimeter is equal to the 1 liter.
So,
4) Since, 1 quart = 0.946353 L
5) Since,The 1 cubic centimeter is equal to the 1 milliliter.
So, 1 millimeter ≠ 1 deciliter
6) Since,1 gram = 0.035274 ounces
So, 1 gram ≠ 1ounce
