ANSWER:
ABD= 37°
DBC= 15°
x= 5


EXPLANATION:

1) Write an equation.
(7x+2)+(3x)=52

2) Combine like terms.
10x+2=52

3) Subtract 2 from both sides.
10x=50

4) Divide by 10 on both sides.
x=5

Next, we will plug this x value in to find the measures of the angles.

7x+2
1) Substitute 5 for x.
7(5)+2

2) Multiply 7 and 5
35+2

3) Add
ABD= 37°

Onto angle DBC...

3x
1) Plug 5 in for x.
3(5)

2) Multiply
DBC= 15°

How much money should a student place in a time deposit in a bank that pays 1.1% compounded annually so that he will have Php 20
STatiana [176]

Let us say that:<span>
   P = present value
   F = future value
    i = interest rate
   n = period

P = F / [ (1 + i ) ^n ]
P = 200000 / [ (1 + 0.011) ^6 ]
P = 187293.65

<span>Therefore the student must put up Php 187,293.65</span></span>

If f(x)=8x and g(x)=2x+1, what is (f×g)(x)
Sav [38]

Answer:

(f * g)(x) has a final product of 16x² + 8x.

Step-by-step explanation:

When you see (f * g)(x), this means that we are going to be multiply f(x) and g(x) together.

<em>f(x)=8x</em>

<em>g(x)=2x+1</em>

Now, we multiply these terms together.

(8x)(2x + 1)

Use the foil method to multiply.

16x² + 8x

So, the product of these terms is 16x² + 8x.
