Answer:

m<BCD  is 62 degrees

Step-by-step explanation:

From the diagram given, both triangles are similar triangles and triangle CAB is isosceles in nature;

Hence;

m<CAB = m<CBA

Also

m<CAB + m<CBA = m<BCD

31 + 31 = m<BCD

Swap

m<BCD = 31 + 31

m<BCD  = 62 degrees

hence the measure of m<BCD  is 62 degrees

A piece of cardboard measuring 9 inches by 11 inches is formed into an open-top box by cutting squares with side length x from e
Alika [10]

Answer:\left ( 11-2x\right )\times \left ( 9-2x\right )\times \left ( x\right )

Step-by-step explanation:

Given data

breadth=9 in

Length=11 in

Now a square of side x is cutted for each corner such that the cardboard is made into a open-top box with

length=11-2x

breadth=9-2x

height=x

Here substract 2x because from both sides of length and breadth x units are reduced.

therefore volume of new open-top box is

Volume(v)=\left ( 11-2x\right )\times \left ( 9-2x\right )\times \left ( x\right )

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6
vodka [1.7K]

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial -3x^4+2x^3-x^2+6 through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial -3x^4+2x^3-x^2+6 .

(x+1)(-3x^3)=-3x^4-3x^3

We subtract this from the original -3x^4-(-3x^4)+2x^3-(-3x^3)-x^2+6.

This leaves 5x^3-x^2+6. We repeat the step above.

(x+1)(5x^2)=5x^3+5x^2.

We subtract this from 5x^3-(5x^3)-x^2-(5x^2)+6=-6x^2+6. We repeat the step above.

(x+1)(-6x)=-6x^2-6x.

We subtract this from -6x^2-(-6x^2)+0x-(-6x)+6=6x+6. We repeat the step above.

(x+1)(6)=-6x+1.

We subtract this from 6x-(6x)+6-(6)=0. There is no remainder. This means (x+1) is a factor.

Measure of a verticle angle is 7x+182 and another angle is 9x+194 solve for x
disa [49]
The measures of 2 vertical angles are always equal, so we have:

7x+182=9x+192.

Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x. 

Thus, x=-6.


This means that the angles are:

i) 7x+182=7(-6)+182=182-42= 140(degrees).

ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)


Answer: x=-6</span>
