What is the value of the expression below when x=4x=4? 7x^2 +8x-7 7x 2 +8x−7
Vinil7 [7]

Answer: 137

Step-by-step explanation:

The given expression: 7x^2 +8x-7

We need to find the value of the expression when x=4.

So we just use the substitution property and substitute the value of x= 4 in the given expression , we get

7(4)^2+8(4)-7\\\\= 7(16)+32-7\\\\= 112+25\\\\=137

Hence, the value of the expression at x=4 is 137.

Alekssandra [29.7K]

Ans:

The solve for x:

2.41x+3.65(248-x)=622.48

2.41x+3.65×248-3.65x=622.48

2.41x-3.65x+905.2=622.48

-1.24x=622.48-905.2

-1.24x= -282.72

x= -282.72÷ -1.24

x=228

Pounds of nuts nper pound $2.41should be included:

228× $2.41

=549.48
