Answer:
Step-by-step explanation:
hello :
5(x + 7)² = 245
(x + 7)² = 49
x=0 is solution but you have other solution -14 because :(-14+7)² = (-7)² =49
here is an solution Step-by-step :
(x + 7)² = 49 means : (x + 7)² = 7²
(x + 7)² - 7²=0 use identity : a²-b² = (a-b)(a+b)
a=x+7 and b= 7
(x+7-7)(x+7+7) = 0
x(x+14)=0
x=0 or x+14=0
so : x=0 or x= -14
<u>Question Correction</u>
Simon fills a container with 38 1-in, cubes. The container is a box of dimension 4 in. by 3 in. by 4 in.,How many more 1 in cubes does the container need to be completely filled?
Answer:
10 1-in cubes
Step-by-step explanation:
First, we determine the Volume of the box.
Volume of a Rectangular Prism =Length X Height X Width
Volume of the box = 4 X 3 X 4= 48 cubic inches
To fill the box container, we would need 48 1 in cubes.
Since Simon already filled the container with 38 1-in, cubes.
Number of 1-in. cubes required to fill the box
=48 -38
=10.
Simon would need 10 1-in cubes to fill the box.
Answer: She baked 108 cookies!
Step-by-step explanation: I did : (6x8) and it gave me (108) and too check my answer i did (108 divided my 6) it gave me 18.

He ate 7/12 of the pizza because 1x4=4, 1x3=3, 4+3=7, and 4x3=12.
Hope that helps.
