Is there supposed to be a picture? I don’t see one.
Ok so
Q.1=B
Q.2=B
Q.3(a)=(d-45)+m+65
(b)=d+m+20
Answer:
Step-by-step explanation:
I don't know exactly how simplified it will be, but you can get the square root smaller.
180: 2*2 * 3*3 *5
For every pair of prime factors you can take 1 of the pair outside the the square root and throw the other one away
sqrt(2*2*3*3*5) = 2 * 3 * sqrt(5) = 6*sqrt(5)
4^45
When you have exponents like that, you have to multiply them together. So, 9*5 =45
Let's solve your equation step-by-step.
178.98
=
6
(
0.04
m
+
24.9
+
(
0.1
)
(
24.9
)
)
Step 1: Simplify both sides of the equation.
178.98
=
6
(
0.04
m
+
24.9
+
(
0.1
)
(
24.9
)
)
178.98
=

178.98
=
(

(Combine Like Terms)
178.98
=
0.24
m
+
164.34
178.98
=
0.24
m
+
164.34
Step 2: Flip the equation.
0.24
m
+
164.34
=
178.98
Step 3: Subtract 164.34 from both sides.
0.24
m
+
164.34
−
164.34
=
178.98
−
164.34
0.24
m
=
14.64
Step 4: Divide both sides by 0.24.
0.24
m
0.24
=
14.64
0.24
m
=
61
Answer:
m
=
61
