Answer:
10
Step-by-step explanation:
Since line 1 // line 2,
11/22=5/x [Theorem]
1/2=5/x
x=10
Answer:
12
Step-by-step explanation:
Simplify \frac{4}{5}G
5
4
G to \frac{4G}{5}
5
4G
.
\frac{4G}{5}+42=2.8G+18
5
4G
+42=2.8G+18
Multiply both sides by 5.
4g + 210 = 14g + 90
Simplify
14G + 90 - 4G to 10G + 90
Subtract 90 from both sides.
210-90=10G210−90=10G
Simplify 210-90210−90 to 120120.
120=10G120=10G
Divide both sides by 1010.
\frac{120}{10}=G
10
120
=G
Simplify \frac{120}{10}
10
120
to 1212.
12=G12=G
Switch sides.
G=12G=12
SORRY ABOUT ALL THIS WORK...
<span>Here let the quadratic equation be ax^2 + bx + c
We know that a=5 from the question.
Since the roots are 6 and 2, the quadratic equation would take the form of a product like (a1x-b1)(a2x-b2).
However, let's assume that a2=1 and b2=6,
Since a=5, a1=5, then 5x-b1=5(x-2). Solving this shows that b1=10
So, the equation is (5x-10)(x-6)</span>
The third one I think I'm not sure
