Stitu wants to cut square pieces of chart paper which is 48 cm long and 32 cm wide .If she is able to get 6 equal pieces ,then f
alisha [4.7K]

Answer:

Length of each piece = 16cm.

Step-by-step explanation:

Since the chart paper is 48cm x 32cm in size, finding the total area of the paper would be A = l x w, where l=length of the paper and w=width.

A = 48 x 32 = 1536cm²

Since Stitu was able to get 6 equal pieces, then we can take the total area and divede by 6:

\frac{1536}{6} = 256

Since 256cm² represents the area of each square, we can take the square root of this number to find the length of just one square since the formula for the area of a square is A=s², where s=the length of one side:

s² = 256 so √s² = √256 or s = 16cm

Find K if 4 x square - 2 X square + kx + 5 leaves a remainder -10 when divided by 2x+1​
ella [17]

Answer:

k = 31

Step-by-step explanation:

Given

f(x) = 4x^2 - 2x^2 + kx + 5

r = -10 --- remainder

d = 2x + 1 --- divisor

Required

Find k

We have:

d = 2x + 1 --- divisor

Equate to 0

2x + 1 = 0

Solve for x

2x = -1

x  =-0.5

This means that:

f(-0.5)=-10

So, we have:

4*(-0.5)^2 - 2*(-0.5)^2 + k*-0.5 + 5 =-10

0.5 -0.5k + 5 =-10

Collect like terms

-0.5k=-10-5-0.5

-0.5k=-15.5

Solve for k

k = -15.5/-0.5

k = 31
