Answer:

A. How much flour did she use for both cakes?

1 3/20 lb flour

B. If she started with a 5lb. Bag, How much flour does she have left?

3 17/20 lb

Step-by-step explanation:

Penny used 2/5lb. Of flour to bake a vanilla cake. She used another 3/4lb. Of flour to bake a chocolate cake

A. How much flour did she use for both cakes?

We solve the above question by adding up the pound of flour used for both cakes.

2/5lb Of flour + 3/4lb Of flour

Lowest common denominator = 20

= 8 + 15/20

= 23/20

= 1 3/20 lb flour

B. If she started with a 5lb. Bag, How much flour does she have left?

This is calculated as:

5 lb - 1 3/20 lb

= 3 17/20 lb

How do you find the sum of cube ?
SIZIF [17.4K]

Answer:

(2x+5)(4x^{2} -10x+25)=0

Step-by-step explanation:

Given:

The given equation is.

8x^{3} +125=0

Find the some of cube.

Solution:

8x^{3} +125=0

2^{3}x^{3} +5^{3}=0

(2x)^{3} +5^{3}=0----------(1)

The sum of the cube formula is given below.

(a^{3} +b^{3})=(a+b)(a^{2} -ab+b^{2} )-----------(2)

By comparing equation 1 and equation 2

a=2x, b=5

substitute a and b value in equation 2

((2x)^{3} +5^{3})=(2x+5)((2x)^{2} -(2x)(5)+5^{2})

((2x)^{3} +5^{3})=(2x+5)(4x^{2} -(10x)+25)

((2x)^{3} +5^{3})=(2x+5)(4x^{2} -10x+25)

Therefore the sum of the cube (2x+5)(4x^{2} -10x+25)=0
