Rewrite it in the form a^2 + 2ab + b^2, where a = 2x and b = 3
(2x)^2 + 2(2x)(3) + 3^2
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
<u>(2x + 3)^2</u>
Answer: 120
Step-by-step explanation:
1st- find out how many hotdogs she eats every hour—
60/12 = 5
5x4=20
She eats 20 hotdogs every hour so next you would multiply
6x20=120
Hope this helped:)
Answer: 8 cubes
Step-by-step explanation:
Volume of a rectangular prism is length × height × width
Length=7 1/2
Width= 15 1/2
Height=12
Volume of the prism is therefore:
7 1/2×12×15 1/2= 1395cm3
No of cubes with edge length 1/2 to fit into the prism will be:
Volume of cube is L*W*H
1/2*1/2*1/2= 1/8cm3
Therefore the no of cubes to fit into the Prism will be:
1395/(1/8)= 11160 cubes.
If one was stuck,the number of 1/2 edge length
cube to fit into 1cm will be:
1/(1/8)= 8 cubes
25% is .25 as a decimal 100*.25=25 so 25% of 100 is equal to 25 because, 25% goes into 100% 4 times so we immediately know that where looking for a number that can go into 100 4 times and it just so happens that 25=25 is true and 100=100 is true so are answer is literally in the question.
