Daniel [21]

Answer:

A) 1 : 4

B) 1 : 2

C) Base of M = 10 units

Step-by-step explanation:

A)

The ratio of the area of triangle M to triangle N

\frac {40}{160}= \frac{1}{4} = 1 : 4

B)

The ratio of the side lengths of triangle M to triangle N

\sqrt{ \frac {40}{160}} = \sqrt{\frac{1}{4}} \\\\={\frac{1}{2}} \\\\=1 : 2

C) Let the base of triangle M be b units.

\sqrt{ \frac {40}{160}} = \frac{b}{20}\\\\\frac{1}{2}=  \frac{b}{20}\\\\2b = 20\\\\b = \frac{20}{2} \\\\b = 10

G(x) = 30x + 5<br><br> h(x) = 10x – 15<br><br> Find h(–3) + g(–5)
kenny6666 [7]

Answer:

The answer is: -190

Step-by-step explanation:

First, you need to input the -3 into the h(x) equation as follows:

h(-3) = 10(-3) - 15, then solve.

h(-3) = -30 - 15

h(-3) = -45.

Then you do the same for g(-5).

So, g(-5) = 30(-5) + 5

g(-5) = -150 + 5

g(-5) = -145.

Now you add the -45 and -145.

h(-3) + g(-5) = -45 - 145

h(-3) + g(-5) = -190.
