It equals 23. 3+4(5) is basically saying 3+ 4 x 5 and with PEMDAS multiplcation is done first. so 4 x 5= 20. 20 + 3= 23. Hope I helped

Answer:
33.8
Step-by-step explanation:
1) Use Phythagoras theorem to get RS ↓

2) RS = RQ
therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

Hope this helps =)
Answer: q³⁰
Explanation:
First just solve the first part using the exponent rules
p²q⁵ becomes 1/p-⁸q-²⁰ then we flip the fraction so the exponents become positive. Now we have p⁸q²⁰.
Before multiplying the other equation, we must simplify. p-⁴q⁵ becomes 1/p⁴q-⁵ and since it's the exponents being raised to a power we simply multiply the inner exponents times the outer exponent which yields 1/p⁸q-¹⁰. We must make q-¹⁰ positive so we will then bring it to the numerator of the fraction which gives us: q¹⁰/p⁸.
Multiply q¹⁰/p⁸ * p⁸q²⁰/1 = p⁸q³⁰/p⁸ divide the p exponents by each other which yields 0 since when u divide exponents you just subtract them so 8 - 8 = 0. Your answer is now q³⁰/1 or just q³⁰
