Answer» GIVEN:A rectangular box with
What To Find:We ave to find the volume of the rectangle box. How To Find:To find the volume of the box, we will use,
Solution:Using the formula, ⇒ Volume = Height × Length × Breadth Substitute the values, ⇒ Volume = (h) × (7h) × (7h - 2) Remove the brackets, ⇒ Volume = h × 7h × 7h - 2 Take variable and numbers seperately, ⇒ Volume = (h × 7h × 7h) - 2 Multiply and solve, ⇒ Volume = 49h - 2 cm³ ∴ THUS, the volume of the rectangular box 49h - 2 cm³. |

Answer» Answer: 1 How do you factorise (x+2)2–(2x+1)2 completely? Super fast, super safe charging. Joseph DeAgostino Answered January 15, 2020 How do you factorize (x+2) 2 –(2x+1) 2 completely? Answer: CONFUSED at first. But: x2−y2=(x+y)(x−y) (x+2)2−(2x+1)2 = ((x+2)+(2x+1))((x+2)−(2x+1)) =(3x+3)(−x+1) = 3(x + 1)(1 - x) Harikirtan Worlu Michael Tam Answered September 19 Method 1: Difference of squares (x + 2)^2 - (2x + 1)^2 = ((x + 2) + (2x + 1))((x + 2) - (2x + 1)) = (3x + 3)(x + 2 - 2x - 1) = 3 (x + 1)(-x + 1) = -3 (x + 1)(x - 1) Method 2: Simplify to collect LIKE terms, then factor (x + 2)^2 - (2x + 1)^2 = x^2 + 4x + 4 - (4x^2 + 4x + 1) = x^2 + 4x + 4 - 4x^2 - 4x - 1 = -3x^2 + 3 = -3 (x^2 - 1) =- 3 (x + 1)(x - 1) Method 3: Substitution Let u = x + 2. Then 2u = 2x + 4. 2u - 3 = 2x + 1 (x + 2)^2 - (2x + 1)^2 = u^2 - (2u - 3)^2 =u^2 - (4U^2 - 12u + 9) = u^2 - 4u^2 + 12u - 9 = -3u^2 + 12u - 9 = -3(u^2 - 4u + 3) = -3 (u - 1)(u - 3) = -3 ((x + 2 - 1)(x+ 2 - 3) = -3 (x + 1)(x - 1) Out of the 3 methods, method #1 is the most direct. |

The hypotenuse and base of right triangle are 20cm and 16cm. What should be subtracted from the length of the height to get the least natural number? |
|
Answer» Given : The hypotenuse and base of right TRIANGLE are 20cm and 16cm. To Find : What should be subtracted from the length of the height to get the least natural NUMBER Solution: Apply Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is EQUAL to the sum of the squares of the other two perpendicular sides. Height² = hypotenuse² - base² => Height² = 20² - 16² => Height² = (20 + 16)(20 - 16) => Height² = (36)(4) => Height² = ( 6²)(2²) => Height = ( 6 )(2 ) = 12 cm Length of height = 12 Least natural number = 1 Hence 12 - 1 = 11 11 should be subtracted from the length of the height to get the least natural number Learn More: using the concept of Pythagoras theorem CONSTRUCT a segment of ... draw a tangent segment of length √12 cm the circle with centre o ... |

→ Find the difference between each pair of items in mm.(a) Two nails of 2.5 cm and 33 mm. _______(b) Two sticks of length 42 mm and 2 cm 8 mm. _______(c) Two wire of length 13.7 cm and 11.5 cm. ________ |
Answer» Answer:a) ✮We know that: 1 cm = 10mm So, 2.5cm = 25mm ✮Solution: (33-25)mm = 8MM Therefore, The difference between two nails are 8mm. b) ✮We know that: 1cm = 10mm So, 2 cm = 2×10 = 20mm and 8mm = 20+8mm = 28mm ✮Solution: (42-28)mm = 14mm Therefore, The difference between two STICKS are 14mm. c) ✮We know that: 1cm =10mm So, 13.7cm = 13.7×10 = 137mm And, 11.5cm = 11.5×10 = 115mm ✮Solution: (137-115)mm = 22mm Therefore, The difference between two wires are 22mm. |
