Ling tried to solve an equation step by step. -2q + 11 = -32

-2q = -43 Step 1

q= 21.5. Step 2

Find Ling's mistake.

Step 1
Step 2​

No error

Step-by-step explanation:

Ling tried to solve an equation step by step.

Step 1.

-2q + 11 = -32

Step 2.

Subtract 11 from both sides,

-2q + 11 -11 = -32 -11

-2q = -43

Step 3.

Dividing both sides by 2,

q = 21.5

Hence, the calculation has no error.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
