Yusuf tried to solve an equation step by step. \qquad\begin{aligned} \dfrac14r+2&=10\ \\ \dfrac14r&=12&\green{\text{ Step } 1}\ \\ r&=48&\blue{\text{Step } 2}\ \end{aligned} 4 1 r+2 4 1 r r =10 =12 =48 Step 1 Step 2 Find Yusuf's mistake.

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

Iknow its nothing to do with education, but what type of thing should i wrote here? ? : ) its for mcdonald's btw.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
