Area of Rhombus =
Diagonal DB = 2×8 = 16
To find AC, we substitute into the formula the area 168 in² and DB of 16 in
Area =
inches
Answer: B
Answer:
b=9 and b=-21
Step-by-step explanation:
first step: move 195 to the other side by adding to get:
b^2+12b=189
now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36
b^2+12b+36=189+36
next factor b^2+12b+36.
(b+6)^2=225
square root both sides to get:
b+6=15 and b+6=-15
solve by subracting 6 to both sides and you get the 2 final answers.
b=9 and b=-21
Answer:
m × 3 is the answer broooooooooooooo
<span>If you would like to calculate (-5a^3 - 2a^2) + (6a^3 + 9a^2 + 8a), you can do this using the following steps:
</span>(-5a^3 - 2a^2) + (6a^3 + 9a^2 + 8a) = <span>-5a^3 - 2a^2 + 6a^3 + 9a^2 + 8a = a^3 + 7a^2 + 8a
</span>
The correct result would be <span>a^3 + 7a^2 + 8a.</span>
Step-by-step explanation:
f(x) = integral (-8x) dx = -4x^2 + C
f(1) = -3 = -4 + C
C = 1
f(x) = -4x^2 + 1
