Answer:

$(x-5)(x+8)=x^2+3x-40$

Step-by-step explanation:

So we have the expression:

$(x-5)(x+8)$

To multiply, distribute the left to the terms on the right:

$=(x-5)(x)+(x-5)(8)$

Distribute:

$=(x^2-5x)+(8x-40)$

Combine like terms:

$=(x^2)+(-5x+8x)+(-40)$

Simplify:

$=x^2+3x-40$

Therefore:

$(x-5)(x+8)=x^2+3x-40$

The diagonals of a parallelogram ABCD intersect at O.find ar(AOB),if ar(ABCD)is 44cm^2

prisoha [69]

Answer:

$11\text{ cm}^2$

Step-by-step explanation:

Given: In a parallelogram ABCD, diagonals intersect at O and ar(ABCD) is $44 \text{cm}^2$ .

We need to find the area of triangle AOB.

We know that each diagonal divide the parallelogram in two equal parts and diagonals bisect each other.

It means both diagonals divide the parallelogram in 4 equal parts.

$ar(AOB)=\dfrac{1}{4}\times ar(ABCD)$

$ar(AOB)=\dfrac{1}{4}\times 44$

$ar(AOB)=11$

Hence, the values of ar(AOB) is $11\text{ cm}^2$ .

The Rectangular rug has side lengths of 3 and 4 feet. What is the length of the diagonal?

lesya [120]

the formula to find the diagonal would be

a^2+b^2=c^2

3^2+4^2= 9+16=25

the square root of 25 is 5

5^2=25

so your diagonal is 5 ft

The best fit line is given by the equation y = 0.404x - 5.18, where y represents the height of the plant above ground level, and

IRISSAK [1]

Step-by-step explanation:

<u>The line of best fit given:</u>

y = 0.404x - 5.18

<u>It is given in the slope-intercept form:</u>

y = mx + b, where m- slope, b - y-intercept

The slope is this situation is m = 0.404 cm and it represents the average growth rate of the plant in one day.

It seems reasonable but without means of control it is difficult to trace the growth while still under the ground, during the first 13-14 days.
