8(5x+ 2) = 296 how to solve this

x = 7

Step-by-step explanation:

8(5x + 2) = 296

40x + 16 = 296

40x = 280

x = 7

x=7

Step-by-step explanation:

➼Okay, so first thing you need to do is to distribute the 8 to everything in the parentheses:

8(5x+ 2) = 296

8 times 5x

8 times 2

(8 x 5x) + (8 x 2) = 40x + 16

➼Now you solve for x

40x+16=296

➼to get rid of 40 you have to do the opposite and divide it by everything

40x+16=296

40/40=0

16/40=0.4

296/40=7.4

➼all adds up to x + .4 = 7.4 but to get the x alone you need to get rid of the .4, we'll do this by doing the opposite and subtract it from everything

.4-.4=0

7.4-.4=7

➼so in conclusion

x=7

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
