Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 7x-2

Group 2: 21x3-6x2

Pull out from each group separately :

Group 1: (7x-2) • (1)

Group 2: (7x-2) • (3x2)

-------------------

Add up the two groups :

(7x-2) • (3x2+1)

A right Triangle is shown. if m angle H= 68°, What is GI? show work if you can and explain to me I don't understand

Answers

Ok, so we've been told that the angle H=68 degrees.

Let's now flip the right angled triangle 90 degrees clockwise.

If we do so, it turns out we'd have to find the opposite length of the right angled triangle (Opp) which is GI. We know that we have the adjacent (Adj) length of this triangle which is in fact 2cm. What we also know is that:

tan(β)=Opp/Adj *Whereby "β" is an angle.

As β=68 degrees, Opp=GI and Adj=2:

tan(68)=GI/2

Therefore:

GI = 2 * tan(68)

GI = 4.95 cm (to 2 decimal places)

If 4x+5y=10 and x+3y = 8 then (5x+8y)/3=

Answers

First set up a system of equations and solve.

4x+y=10
x+3y=8
In order to have one variable cancel out, I will multiply the top by -3.

-12x-3y=-30
x+3y=8
____________
-11x=-22
x=2

Then plug the x value into one of the original equations.

(2)+3y=8
3y=6
y=2

Now plug both into the final equation:
5(2)+8(2)/3
(10+16)/3
26/3
8.667 is the answer or 26/3.

Answer:

13y/3 is the answer
