In three days Speedy the squirrel ate 30 peanuts. On both the second and third day, Speedy ate 7 peanuts more than on the day before. How many peanuts did Speedy eat the first day?

the answer is my nballs

Step-by-step explanation:

3 peanuts

Step-by-step explanation:

x represents peanuts eaten on first day

30 peanuts eaten in 3 days

7 more peanuts eaten every day after first day which gives the equation:

x+(x+7)+(x+14) = 30

3x+21 = 30

3x = 9

x=3

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
