Help I don't know what to put ​

7

Step-by-step explanation:

plug in 3 where ever there is x

so

(4(3)+2)-7

use PEMDAS to solve from left to right

P: Parenthesis

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

so we got p so we do that first

(4(3)+2) --> 4 × 3 = 12 (Multiplication first like in PEMDAS)

(12+2) = 14

so then in the equation you are left with

(14)-7 = 7

answer is 7

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
