Answer:
Step-by-step explanation:
WE willl solve the question for the following equation 
1. Add 8c on both sides


2. Add 10 on both sides


3. Substract 2c on both sides


4. Divide both sides by 2


Then, the equation is solved.
Answer:
4x² - 20x + 16
Step-by-step explanation:
Given
(4x - 4)(x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(x - 4) - 4(x - 4) ← distribute both parenthesis
= 4x² - 16x - 4x + 16 ← collect like terms
= 4x² - 20x + 16
Answer:
8.8
Step-by-step explanation:
Alright so since you know the length of the side opposite the 27 degree angle and you need to find the hypotenuse, you'll use sin (opposite/hypotenuse) . so you do sin 27= 4/x and then when you do these trigometric ratios something my geo teacher taught me is that if the variable is in the denominator then you have to do the length of the side you know /sin/cos/tan of whatever angle you know. so here you insert in your calculator 4/sin 27 (make sure ur calculator is in degree mode you can check this by doing sin 30 and seeing if it equals 1/2 and if it doesnt you need to search online on how you do degree mode) and you get 8.8108. which rounds to 8.8
Answer:
900°
Step-by-step explanation:
interior angles of a polygon = (n−2)×180°, where n is number of sides
for heptagon it is: (7-2)×180°= 900°
