Can someone please help me with this

Explanation:

The congruent base angles are D and E. Opposite those angles are the sides CE and CD. These opposite sides are the same length.

CE = CD

16x-27 = 4x+9

16x-4x = 9+27

12x = 36

x = 36/12

x = 3

This x value then leads to the following:

We see that CD and CE are both 21 units long, which helps confirm we have the correct x value.

x=3

CD= 21

DE= 16

CE= 21

Step-by-step explanation:

First, let's solve for x. Since angles D and E are congruent, you know that the length of lines CD and CE are equal. So, let's set up the equation by putting lines CD and CE equal to each other.

CD=CE

4x+9=16x-27

x= 3

Now that we've solved for x, we can now plug in the value into the other expressions to find the side lengths.

CD=4x+9

CD=4(3)+9

CD= 21

CE=16x-27

CE=16(3)-27

CE= 21

DE= 7x-5

DE= 7(3)-5

DE= 16

answer: answer

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
