Answer:

Qn1: -37

Qn2: 16

Qn3:-33.6

Step-by-step explanation:

<u>Qn1:</u>

k(4) = -4*4-6 = -16-6 = -22

m(5) = (5^2)-8*5=-15

k(4)+m(5)= -22+ (-15)= -37

<u>Qn2:</u>

m(-2)= 4 -8*(-2)= 20

n(10) = 2 -6 = -4

20+ (-4)=16

<u>Qn3:</u>

n(-100)= -20-6 = -26

k(-8) = -1.6 -6= -7.6

-26+ (-7.6) = -33.6

An in ground rectangular pool has a concrete pathway surrounding the pool. if the pool is 16 feet by 32 feet and the entire area
Anastasy [175]
1. Let's call:
 
 x: the width of the walkway.
 b: 2x+16 (there is a widht "x" of the walkway on each side).
 h: 2x+32  (there is a widht "x" of the walkway on each side).
 A: 924 ft^2 ( the area of the pool of including the walkway).
 
 2. The area of a rectangle is:  
 
 A=(b)(h)
 
 b: the base of the rectangle (2x+16)
 a: the height of the rectangle (2x+32)

 3. Then, we have a quadratic equation:
 
 924=(2x+16)(2x+32)
 4x^2+64x+32x+512-924=0
 4x^2+96x-412=0
 
 4. We apply the quadratic formula to find the value of "x":
 
 x=(-b±√(b^2-4ac))/2a
 
 x=3.71
 
 The answer is: The width of the walkway is 3.71 ft

jake added 1/8 cup of sunflower seeds and 4/5 cup of banana chips to his sundae. which is the best estimate of the total amount
bagirrra123 [75]

Jake added \frac{37}{40} cup of toppings to his sundae.

Step-by-step explanation:

Given,

Amount of sunflower seeds added = \frac{1}{8}\ of\ a\ cup

Amount of banana chips added = \frac{4}{5}\ of\ cup

Total = Amount of sunflower seeds + Amount of banana chips

Total = \frac{1}{8}+\frac{4}{5}

Taking LCM = 40

Total = \frac{5+32}{40}\\\\Total = \frac{37}{40}

Jake added \frac{37}{40} cup of toppings to his sundae.

The area of a triangle is 24sq inches. If the base of the triangle is 6 inches, what is the height?
Helen [10]

Answer:

8 inches

Step-by-step explanation:

To find the area of a triangle, we use the formula

A = 1/2 bh where b is the length of the base and h is the height

A = 24 and b = 6

24 = 1/2 (6) * h

24 =3h

Divide each side by 3

24/3 = 3h/3

8 =h

The height is 8 inches

Nancy and bill collect coins. Nancy has x coins. Bill has 5 coins fewer than five times the number of coins Nancy has. Write and simplify an expression for the total number of coins Nancy and bill have . Simplify your answer .

Let

Number of Nancy's coins = x

Number of Bill's coins = 5x - 5

Total number of coins Nancy and bill have = Number of Nancy's coins + Number of Bill's coins

= x + (5x - 5)

= x + 5x - 5

= 6x - 5

Total number of coins Nancy and bill have = 6x - 5
