What is the value for x?

schepotkina [342]

Right of the bat, I know the measure of angle C equals 73° because of the Isosceles Base Angle Theorem. Then, due to the Triangle Sum Theorem, I know that all of the measures in the triangle must add to 180°. To find this, just subtract 73 and 73 from 180. Finally, because angle B equals (6x + 4) and 34°, just set them equal to each other to find the value of x.

180 - 73 - 73 = measure of angle B
34° = measure of angle B

6x + 4 = 34
- 4 - 4
6x = 30
6x / 6 = 30 / 6
x = 5

Hope this helps!

max invests $6000 in a savings account for 3 years. the account pays compound interest at a rate of 1.5% per year for the first

madam [21]

Answer:

2.1%

Step-by-step explanation:

The formula for compound interest is given as:

$A=P(1+I)^n\\\\P-Principal \\A-amount\\i-compound \ interest \ rate$

Given the Principal amount as $6000, and the rate in the first two years as 1.5%:

$A=P(1+i)^n\\\\A_2=6000(1+0.015)^2\\\\A_2=6181.35$

We compound $A_2$ for 1 year at rate i to obtain $6311.16:

$A=P(1+i)^n, n=1, i=i, P=6181.35, A=6311.16\\\\6311.16=6181.35(1+i)^1\\\\\frac{6311.16}{6181.35}=(1+i)\\\\i=\frac{6311.16}{6181.35}-1\\\\i=0.02100$

Hence, the compound interest rate in the third year is 2.1%

Rachel is using grouping to find the factors of a quadratic expression. She has reached the step shown below. Determine the fact

Feliz [49]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

If the factored form is given by

$(3x-4)(x+2)$

Then its standard form will be given by

$(3x-4)(x+2)\\\\=3x^2+6x-4x+8\\\\=3x^2+2x+8$

if factored form is given by

$(3x+2)(x+4)$

Then its standard form will be given by

$(3x+2)(x+4)\\\\=3x^2+12x+2x+8\\\\=3x^2+14x+8$

Hence, only first option is correct.
