Answer:
8^8
Step-by-step explanation:
8^3 x 8^5
We know that a^b * a^c = a^(b+c)
8^(3+5)
8^8
Answer:
63 inches
Step-by-step explanation:
the formula for the area of a triangle is
a = 1/2 bh
plug in the numbers
a = 1/2(9)(14)
9 times 14 is 126
a = 1/2(126)
half of 126 (or 126 divided by 2)
area = 63 inches
Answer:
63
Step-by-step explanation:
88 - 25 = 63 did it on paper
Answer:
11
Step-by-step explanation:
Let's call the white marbles w and the red marbles r. We can write:
w + r = 16 (1)
w = 3r - 4 (2)
3r - 4 + r = 16 (3) (Substitute (2) into (1))
4r = 20 (simplify)
r = 5 (divide by 4) which means w = 16 - 5 = 11
-19x-11 should be the answer... if the 19 and x aren’t combined then the answer is x-30
