2x2x2 = 8
4 x 2 x 2 = 16
16+8 = 24
Answer is A
BD = AC Given. BD cuts AC in half. That's what bisectors do.
BD = BD Reflexive property of a line (it is always equal to itself).
<ADB = <ADC = 90o
DB is perpendicular to AC Given.
<ADB + <ADC = 180o The two are supplementary.
Each angle = 90o Perpendicular means that one line meets another at 90o
2x = 180
x = 90o
Since each of the enclosed angles = 90, two have two triangles congruent by SAS <<<< Answer
Answer:
Step-by-step explanation:
figure one
formula length x width x height
plug in 7 x 2 x 3
volume 42 cm^3
figure 2
formula length x width x height
plug in 3 x 2 x 7
volume 42 cm ^3
X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
