The figure seems like its a parallelogram.

In a parallelogram :
Opposite sides are equal and
Opposite angles are equal
Hence, The side opposite to 9in. is equal to 9in. and the side opposite to 10in. is equal to 10in.

Area of the figure =b×h
= 8×10
=80in.sq.

Area = b x h = 8 in. x 10 in. = 80 in.

Perimeter = 2 x l + 2 x w = 2 x 9 + 2 x 10 = 38 in.

Eugene walked all the way to school at 3 mph then realized she forgot her math book (how could she?!), so she ran back at 7 mph.

Fynjy0 [20]

$\text{Answer: }1\frac{23}{40}\ miles\text{ far she live from school.}$

Explanation:

Since we have given that

Speed at which Eugene walked all the way to school = 3 mph

After realizing that she forgot her math book, she ran back

Speed at which Eugene walked back to her house = 7 mph

Let the distance between her house and her school be x

According to question,

$\frac{x}{3}+\frac{x}{7}=\frac{45}{60}\\\\\frac{7x+3x}{21}=\frac{3}{4}\\\\\frac{10x}{21}=\frac{3}{4}\\\\x=\frac{3\times 63}{4\times 10}=\frac{63}{40}=1\frac{23}{40}\ miles.$

Hence,

$1\frac{23}{40}\ miles\text{ far she live from school.}$

For this,we need to know what's Middle splitting method

In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as px + qx and get desired factors by grouping the terms.

Step-by-step explanation:

$9x {}^{2} - 24x + 16 \\ = > 9x {}^{2} - 12x - 12x + 16 \\ = > 3x(3x - 4) - 4(3x - 4) \\ = > (3x - 4)(3x - 4) \\ so... \\ x = eitherway \: 4$

i.e

Alpha= Beta = 4
