5 goes into 40 8 times than add a zero
Answer:
⇛x=8cm.
Step-by-step explanation:
Given that
PQRS is a square and PQ = (2x+3) cm
and QR = (3x-5) cm
We know that
All sides are equal in a square .
⇛ PQ = QR = RS = PS
⇛ 2x+3 = 3x-5
⇛ 3+5 = 3x-2x
⇛ 8 = x
⇛ x = 8
Therefore, The value of x = 8 cm.
Answer:
- x = 4 is the only real zero
Step-by-step explanation:
<u>Find the zero's of f(x)</u>
- 2x³ - 12x² + 20x - 16 = 0
- x³ - 6x² + 10x - 8 = 0
- x³ - 4x² - 2x² + 8x + 2x - 8 = 0
- x²(x - 4) - 2x(x - 4) + 2(x - 4) = 0
- (x - 4)(x² - 2x + 2) = 0
- (x - 4)(x² - 2x + 1 + 1) = 0
- (x - 4)[(x - 1)² + 1] = 0
- x - 4 = 0 ⇒ x = 4, we already know this
- (x - 1)² + 1 = 0 ⇒ (x - 1)² = - 1, no real solution as the square is never negative
