Answer:

4.11

Step-by-step explanation:

7(p-9)=-34.3

first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get

7p-63=34.3

Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with

7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714

The product of two consecutive square numbers is 144. Work out the two numbers
Sergio [31]

Let the first number be = x

Let the second number which is consecutive be = x+1

As given, the product of two consecutive square numbers is 144

x^{2}*(x+1)^{2}=144

Square rooting both sides we get

x(x+1)=12

x^{2}+x=12

x^{2}+x-12=0

x(x+4)-3(x+4)=0

(x-3)(x+4)=0

x=3 or x=-4

Neglect the negative value so we get x=3

Hence, one number is 3 and the consecutive number is = 3+1=4

The square of the numbers are 9 and 16.
