What is the proper solution to the following equation? answer with correct significant figures. (23.1 + 5.61 + 1.008) × 7.6134 × 8.431 =

(23.1 + 5.61 + 1.008) × 7.6134 × 8.431  

= 29.718 × 7.6134 × 8.431

=1907.55608

The equation is solved in the manner that the term in the bracket is added first then mutiplication is done as according to Bodmas rule, if an equation contains brackets that need to be solved first then other operation that is  division,multiplication, addition and subtraction are performed from left to right .

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
