Carlotta just needs to evaluate both expressions

Say y = 2

3y + 5y³ = 3(2) + 5(2)³ = 6 +40 = 46

8.y**4 <span>   = 8*(2)**4 = 8*(16) = 128

This means that   
</span>3y + 5y³ ≠ 8.y**4

Answer:

Unlike terms

Step-by-step explanation:

3y and 5y^3 are not same

that is these are only like terms.

We can add or subtract only like terms

in Algebra terms are alike if their exponents are same

here first terms exponent is 1

and second term exponent is 5y^3 is 3.

therefore these terms cannot be added t give 8y^4

Sandra throws an object straight up into the air with an initial velocity of 38 ft/s from a platform that is 30 ft above the gro
Makovka662 [10]

Answer:

The answer is C.

Step-by-step explanation:

Given formula h(t)=−16t2+v0t+h0 , where v0 is the initial velocity and h0 is the initial height.

In this case, the initial postion is a platform 30ft above ground so h0=+30

The initial velocity is 38 ft/s straight up into the air so v0=+38

h(t)=-16t2+38t+30

When the object hits the ground, h=0.

h=-16t2+38t+30=0

Simplifying 8t2-19t-15=0

(8t+5)(t-3)=0

t=-5/8 or 3

As time cannot be -ve, t=3s. The answer is C.
