6)

=(4×4-6×2×1+9×1)(2×2+3×1)

=(16-12+9)(4+7)

=13×11

=143 is the answer...

7)

9x(6x−5y)−12x2(6x−5y)

⇒(9x−12x2)(6x−5y)

⇒3x(3−4x)(6x−5y).

Hence, the answer is 3x(3−4x)(6x−5y).

There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me

i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)

In ΔNOP, the measure of ∠P=90°, the measure of ∠O=17°, and OP = 8.6 feet. Find the length of PN to the nearest tenth of a foot.
SVEN [57.7K]

The length of PN is 2.63 feet

<u>Explanation:</u>

<u />

Given:

∠P=90°,

∠O=17°,

OP = 8.6 feet

PN = ?

The given triangle is a right angle triangle as one angle is 90°

We know:

tan \alpha = \frac{perpendicular}{base}

tan(17^o) = \frac{PN}{OP} \\\\0.3057 = \frac{PN}{8.6} \\\\PN = 0.3057 X 8.6 feet\\\\PN = 2.63 feet

Therefore, the length of PN is 2.63 feet

Gnesinka [82]

Answer:

{(12-4) + (15-8)}x  = 65

Step-by-step explanation:

The amount Amber earns per week

12-4

The amount Nathan earns per week

15 -8

The total amount per week they earn together

(12-4) + (15-8)

Multiply by x weeks

{(12-4) + (15-8)}x

Set this equal to 65 to be the amount they need to equal 65 dollars

{(12-4) + (15-8)}x  = 65
