BC = x

AB = BC - 6

AC = BC + (BC - 6) - 13 = 2BC - 19

AB + AC + BC = 78

substitute:

(BC - 6) + (2BC - 19) + BC = 78

4BC - 25 = 78 |+25

4BC = 103 |:4

BC = 25.75

Answer: 25.75 mm

The shown bellow question answer
Serhud [2]

Answer:

The area of the shape can be divided into the area of the rectangle, and the area of the semi-circle.

The area of the rectangle can be found by 11*4=44

The area of a semi-circle can be found with the formula \frac{1}{2} \pi r^2 where r is the radius.

Since we know the diameter of the semi-circle is 4,

the radius will be 4 ÷ 2 = 2.

Therefore, the area of the semi-circle is \frac{1}{2}\pi 2^2=\frac{1}{2}\pi*4=2\pi

Therefore, the area of the shape is 44+2\pi or 50.283cm^2 (3 decimal places)

Answer:

x = 12

Step-by-step explanation:

By applying geometric root theorem in the given triangle,

\frac{BD}{DC}= \frac{AD}{BD}

BD^2=AD\times DC

x^{2} =16\times 9

x=\sqrt{144}

x=12

Therefore, x = 12 will be the answer.

Some one please help me with these questions I’m struggling :(
Juliette [100K]

Answer: 6) 15 1/10

Step-by-step explanation:

Add the whole numbers and then find a common number for the bottom fraction. So that'd be ten. To get to ten from 2 you'd multiply by five then multiply the top number by five too. That gets you 5/10 and do the same for the other fraction. Get the bottom number to ten then whatever you multiply by do the same to the top. After doing that putting the fractions together which gets you 11/10. That'd make 1 1/10 so that makes it 15 instead of 14 whole

Find the domain and range of the function y = f(x) = r2.=Domain:help (inequalities)Range:help (inequalities)
Juliette [100K]

we have the function

y=f(x)=x^2

the domain is all real numbers -------> interval (-∞, +∞)

the vertex of the vertical parabola is the origin (0,0)

the parabola opens upward

the vertex is a minimum

so

the range is the interval [0, ∞)
