Answer:
x + √x - 6
Step-by-step explanation:
Multiply out (√x-2)(√x+3) using the FOIL method:
Multiply the First terms: x
Multiply the Outside terms: 3√x
Multiply the Inside terms: -2√x
Multiply the Last terms: -6
Now combine these results. We get:
x + √x - 6
Change the percents to decimals (by moving the decimal 2places to the left)
(.24, .38)
Multiply each by 112,483.
(.24x112483, .38x112483)
(26,996, 42,744). You can’t have decimals because people are whole numbers. So round to the nearest whole number
I think the answer will be B 1-9x+C=32
Answer:
1A: 29 units²
1B: √29 units
2, 3, 4. see below
5. between 8 and 8.5
Step-by-step explanation:
1A: Split the given square up into 4 triangles and a square in the centre. You'll get 4 triangles of sides 5 and 2, and a centre square of sides 3.
Area = 4(0.5)(5 x 2) + (3²) = 29 units²
1B: Square root your answer in 1A. √29 units
Alternatively you can use Pythagoras' theorem on one of the triangles. √(5² + 2²) = √29 units
2. The area is exactly 17 units, because the area of a square is the length of its side squared. (√17)² = 17, hence the square's area is 17 units.
3. A number that can be expressed as a fraction (includes whole numbers). E.g. 1/2, 1/7, 4
4. A number that cannot be expressed as a fraction. E.g. π, e, √3
5. Consider the closest square numbers to 70. 70 is closer to 64 than 81 (difference of 6 vs 11). Hence √70 should be closer to 8 than 9. Your answer should be between 8 and 8.5.
