They are complementary angles.
Answer: 15t
Step-by-step explanation: 6t and 9t are like terms, meaning that you can combine them to get 15t.
9.2 x 13.8 = 126.96, now usually to get the area of a triangle we would half this but because we have two of the same triangle we would then have to double it again so they cancel each other out. We then do 6.9 x 9.2 which equals 63.48 and again we have two of the same triangle so no need to half it. So we add the two totals of 126.96 and 63.48 together to get 190.44.
Answer:
Step-by-step explanation:
So first of all, you can rearrange your equations:
4x + 7x = 11 can be rearranged and simplified to x = 11/7
x = y + 1 can be rearranged to y = x - 1
Then you can graph them like normal by plugging in points. It should look like the following picture
It is implied in the given that the tree grows linearly. The equation can be expressed as,
h = mx + b
where m and b are the slope and y-intercept. Convert the 8 in first to feet for the units to be uniform. 8 inches equal 0.75 ft. From the given, the final equation would be,
h = (3/4)x + 5
