Answer:

A. x = 11

Step-by-step explanation:

so, the angle D corresponds to angle T.

therefore, the side BD corresponds to RT.

and CD to ST.

since both triangles are similar, they must have the same angles, and all corresponding sides and other lengths must have the same scaling factor.

so,

RT × f = BD

and the same f must then apply to

ST × f = CD

21 × f = 98

f = 98/21 = 14/3 = 4.666666666...

33 × 14/3 = 15x - 11

11 × 14 = 15x - 11

154 = 15x - 11

15x = 165

x = 11

There is a line whose y-intercept is 7 and whose slope is 8. What is its equation in slope-intercept form?
Annette [7]
Answer:
y = 8x + 7

Explanation:
The equation of the line in slope-intercept form has the following general formula:
y = mx + c
where:
m is the slope of the line = 8
c is the y-intercept = 7

Substitute with the givens in the above formula to get the slope of the line as follows:
y = mx + c
y = 8x + 7

Hope this helps :)

What is the circumference if the diameter is 21in and pi is 22/7
Ede4ka [16]

Answer:

66 in

Explanation:

the circumference can be calculated as:

C=d\cdot\pi

Where d is the diameter and π is 22/7.

So, replacing the values, we get:

C=21\cdot\frac{22}{7}=\frac{21\cdot22}{7}=\frac{462}{7}=66\text{ in}

Therefore, the circumference is 66 in.

(c+d)^2+11(c+d)+30<br><br> Factor completely.
tatyana61 [14]

Answer:

firstable give c+b a polynomial value like x

so its will be x^2+11x+30

after the we have to factor it

30=6×5

and 11=6+5

so its will become

(x+6)×(x+5)=x^2+11x+30

x=c+d

(c+d+6)×(c+d+5)=(c+d)^2+11(c+d)+30

have a great day
