Answer:
x^2+10
Step-by-step explanation:
2x^2+3-(x^2-7)
2x^2+3-×^2+7
x^2+10
Answer:
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
a = 0.1x
b = 0.2y
(0.1x - 0.2y)²= (0.1x)² - 2*0.1x*0.2y + (0.2y)²
= (0.1)²x² - 0.04xy + (0.2)²y²
= 0.01x² - 0.04xy + 0.04y²
Answer:
12.96
Step-by-step explanation:
since it is a square, both sides are equal. to find the area of any square, it is the side squares. since you are given what the area is, simply square root 168.
which is about 12.96
Answer:
y=131°
x=53°
Step-by-step explanation:
∠ ABD and ∠ BDC are supplementary.
The sum of the supplementary angles =180 °
thus y-4+x=180...........i
x and 37° are complementary, that is, they add up to 90°
Thus, x=90-37=53°
Using this value in equation 1 we obtain:
y-4°+53° =180°
y= 180°-53°+4°
y=131°
Answer:
you cannot subtract 12x² from -14x they are not "like" terms
