Answer:
B. 2⁷
Step-by-step explanation:
Whenever you multiply 2 exponents, you add the powers.
(2³)(2⁴)
3 + 4 = 7
2⁷
Y=2×2
y=4
4=-3x-1
now add 3x on both sides
3x+4= -1
now substract 4 on both sides
3x = -5
divide 3 on both side
x=-5/3
y= 4
x= -5/3
There are only 13 multiples of both 3 and 5, since
From these integers, we eliminate any that are also divisible by 4 or 7.
so there are 13 - 4 = 9 such integers.
Answer:
Both A and B
Step-by-step explanation:
sum of opposite interior angles is equal to the exterior angle.
Answer:
w = 7, 1
Step-by-step explanation:
A perfect square is shown by a²-2ab+b²
If you substitute the question into the formula you get:
w²-(2×4×w)+4²
Simplify and you get:
w²-8w+16=9
Factor:
(w-4)²=9
Square Root both sides:
w-4=±3
w=7, w=1
