To solve a quadratic equation using completing the square method,
STEP 1
Divide through by the coefitient of the squared term.
Looking at the solutions of Rashid and Tia, we notice that Rashid did not divide through by the coefficient of
.
Therefore, Rashids solution is wrong.
We solve the equation using completeing the square as follows:
Answer:
90°
Step-by-step explanation:
angle on a straight line=180 and half of 180=90°
Answer:
Step-by-step explanation:
6(5+x) = 30 + 6x
1. Distribute the 6 to both the 5 and the x.
7x5x3 = 105
1. Just multiply them together.
28 - 3(2+4)/9 = 26
1. PEMDAS
2. Add inside the parenthesis: 28 - 3 x 6 / 9
3. Multiply: 28 - 18 / 9
4. Divide: 28 - 2
5. Subtract: 26
Answer:
162 square inch
Step-by-step explanation:
Area = Length * Width
Area =
<h2>Answer: </h2>
We know that,
Length of arc = 2 × 3.14 × 6 × 45/360
Length of arc = 6.28 × 3/4
= 18.84/4
= 4.71units.
