Rewrite each expression more simply: 3y + 8y

1 answer:

6 0

Since they both have the same variable(y) you can add them together like a regular math problem. So:
3y+8y=11y
So your final answer would be 11y.

The height h, in feet, of a ball that is released 4 feet above the ground with an initial velocity of 80 feet per second is a fu

gulaghasi [49]

Answer with Step-by-step explanation:

The height of the ball from the ground as a function of time is given by

$h(t)=-16t^2+80t+4$

The height of the ball at any instant of time can be found by putting the value of time 't' in the above relation as

Part a)

Height of ball after 2 seconds it is released is

$h(2)=-16\times 2^2+80\times 2+4=100feet$

Part b)

Height of ball after 4 seconds it is released is

$h(4)=-16\times 4^2+80\times 4+4=68feet$

I need help with this problem answers is right there but show me how to get that answer

Olin [163]

First you find P which would be 16+17+17 which equals 50. Then you find B which is 1/2•16•15 which equals 120. Next you write the formula which would look like 50(20)+2(120) which equals 1240!

Find the value of x and y

Romashka [77]

Step-by-step explanation:

$\triangle ABC \sim\triangle DEF..(Given) \\ \therefore \frac{AB}{DE} =\frac{BC}{EF}=\frac{AC}{DF}..(CSST)\\\\\therefore \frac{6}{4} =\frac{7}{x}=\frac{8}{y}\\\\ \therefore \frac{6}{4} =\frac{7}{x} \\ \therefore \: x = \frac{7 \times 4}{6} \\ \\\therefore \: x = \frac{28}{6} = \frac{14}{3} \\ \\ \huge \red{ \boxed{ \therefore \: x = \frac{14}{3} }} \\ \\ \because \: \frac{6}{4} =\frac{8}{y} \\ \\ \therefore \:y = \frac{4 \times 8}{6} \\ \\ \therefore \:y = \frac{32}{6} \\ \\ \huge \purple{ \boxed{ \therefore \:y = \frac{16}{3} }}\\ \\$

tangare [24]

Answer:

4r^3+8r^2-5r-10

= 4r^2(r+2)-5(r+2) [Factorise out like terms; distributive law of multiplication to check]

=(4r^2-5)(r+2) [Combine expressions]
