Answer:

I know this is really late but if anyone else needs help I hope this will help those people.

Step-by-step explanation: so expand (3x+5) (X-2) first apply FOIL method: (a+b) (c+d)= ac + ad +bc + bd..... a= 3x, b=5, c=x, d= -2. our end product would be 3xx+3x(-2) + 5x + 5(-2).

Then apply minus-plus rules: +(-a)= (-a)...... we would end up with 3xx-3 times 2x + 5x - 5times 2.

next simplify until we end up with 3x^2 - x- 10

Not 100% sure if this is what your looking for but this is my best educated guess from the question asked.

the length of diagonal of a rectangular field is 23.7 m and one of its sides is 18.8 m. find the perimeter of the field.

katen-ka-za [31]

Answer:

Approximately 66.4 Meters

Step-by-step explanation:

So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.

$a^2+b^2=c^2$

Plug in 18.8 for either a or b. Plug in the diagonal 23.7 for c.

$(18.8)^2+b^2=23.7^2\\b^2=23.7^2-18.8^2\\b=\sqrt{23.7^2-18.8^2} \\b\approx14.4 \text{ meters}$

Therefore, the length is 14.4 meters. Now, find the perimeter:

$P=2l+2w\\P=2(14.4)+2(18.8)\\P=66.4\text{ meters}$

Answer:

○ ³\⁷

Step-by-step explanation:

Since you are multiplying ⁷√x three times, you write it like this first, ⁷√x³, then according to one of the Six Exponential Rules, ⁿ√aᵐ = aᵐ\ⁿ, ⁷√x³ gets rewritten as x³\⁷.
