3(x+5) each side is x+5 so times that by 3. Distribute the 3 to both the x and the 5 to get 3x+15.
Answer:
c = 9/16
Step-by-step explanation:
<h3>step1</h3>
(a-b)²
a² - 2ab + b²
here a = x
b = ?
so
x² - (2)(x)(?) + ?²
Now we can see that -(2x)? = -3x/2
-2x? = -3x/2
cancel -x on both sides
2? = 3/2
? = 3/2 * (2)
? = 3/4
so b = 3/4
<h3>step2</h3>
(x² - 3x + 9/16) = (x-3/4)²
so from the expression we can see that C = 9/16

Answer:What's the problem for question 2? And I may be able to help you with it.
Step-by-step explanation:
Answer: option B is correct
Step-by-step explanation:
The formula for determining the area of cross section of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.
h represents the height of the trapezoid.
From the information given,
a = h1 = 11 inches
b = h2 = 15 inches
If It has an area of 52 inches² , then
52 = 1/2(11 + 15)h
Cross multiplying by 2, it becomes
52 × 2 = (11 + 15)h
104 = 26h
h = 104/26 = 4 inches
