Isabel had 12 pages of history and 12 pages of science assignments to read. It took her 10 minutes to read a page of history. She spent a total of 216 minutes to complete all of her reading assignments.

Let x be the time it took Isabel to read one page of science.

Use the equation editor to enter the equation that represents the problem. The equation should have the form p(x+q)=r, using the variable x and the correct values for p, q, and r.

the equation can be 12(x+10)=216

Step-by-step explanation:

time taken for reading 12 pages of science =12×x

time taken for reading 12 pages of history=12×10=120

total time taken =216

the expression can be 12x+120=216

which expressed in the form p(x+q)=r,, it will be 12(x+10)=216

where p=12

q=10

r=216

hope this helps

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
